Proton magnetic resonance spectra of cubane derivatives. II. Aromatic solvent-induced shifts was written by Edward, John T.; Farrell, Patrick G.; Langford, Gordon E.. And the article was included in Journal of the American Chemical Society in 1976.Application of 60462-27-3 The following contents are mentioned in the article:

Aromatic solvent-induced shifts (ASIS) were measured for a number of substituted cubanes in benzene and pyridine and an additivity rule was derived which allows accurate prediction of these shifts. Protons remote from the substituent show the largest ASIS and these are shown to correlate with substituent electronegativity. Models are discussed for the nature and stereochem. of the solute-solvent interaction. The observed additive shifts arise from independent, transient 1:1 associations of solvent mols. with the electron-deficient sites of all local dipoles in the solute. This study involved multiple reactions and reactants, such as Cubane-1,4-diyldimethanol (cas: 60462-27-3Application of 60462-27-3).

Cubane-1,4-diyldimethanol (cas: 60462-27-3) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Application of 60462-27-3

Proton magnetic resonance spectra of cubane derivatives. I. Syntheses and spectra of mono- and 1,4-disubstituted cubanes was written by Edward, John T.; Farrell, Patrick G.; Langford, Gordon E.. And the article was included in Journal of the American Chemical Society in 1976.Name: Cubane-1,4-diyldimethanol The following contents are mentioned in the article:

The syntheses of a number of monosubstituted and 1,4-disubstituted cubanes are described, together with the measurement and anal. of their 100-MHz 1H NMR spectra. A simple additivity rule is described whereby chem. shifts in CDCl3 can be predicted to within ±0.02 ppm. Both chem. shifts and coupling constants are shown to vary with substituent electronegativity. The derived correlations allow quick and effective identification of cubane derivatives from their 1H NMR spectra, and also aid in the interpretation of the more complex spectra of less sym. cage mols. This study involved multiple reactions and reactants, such as Cubane-1,4-diyldimethanol (cas: 60462-27-3Name: Cubane-1,4-diyldimethanol).

Cubane-1,4-diyldimethanol (cas: 60462-27-3) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Name: Cubane-1,4-diyldimethanol

Cubane mols. hold great potential for medicinal chem. applications due to their inherent stability and low toxicity. In this study, we report the synthesis of a cubane derivative phosphoramidite for the incorporation of cubane into small interfering RNAs (siRNAs). Synthetic siRNAs rely on chem. modifications to improve their pharmacokinetic profiles. However, they are still able to mediate sequence-specific gene silencing via the endogenous RNA interference pathway. We designed a library of siRNAs bearing cubane at different positions within the sense and antisense strands. All siRNAs showed excellent gene-silencing activity, with IC50 values ranging from 45.4 to 305 pM. Incorporating the cubane modification in both the sense and antisense strand led to viable duplexes with good biol. activity. To the best of our knowledge, this is the first report of siRNAs bearing a cubane derivative within the backbone. This study involved multiple reactions and reactants, such as Cubane-1,4-diyldimethanol (cas: 60462-27-3Safety of Cubane-1,4-diyldimethanol).

With the burgeoning interest in cage motifs for bioactive mol. discovery, and the recent disclosure of 1,4-cubane-dicarboxylic acid impact sensitivity, more research into the safety profiles of cage scaffolds is required. Therefore, the impact sensitivity and thermal decomposition behavior of judiciously selected starting materials and synthetic intermediates of cubane, bicyclo[1.1.1]pentane (BCP), and bicyclo[2.2.2]octane (BCO) were evaluated via hammer test and sealed cell differential scanning calorimetry, resp. Iodo-substituted systems were found to be more impact sensitive, whereas hydroxymethyl substitution led to more rapid thermo-decomposition Cubane was more likely to be impact sensitive with these substituents, followed by BCP, whereas all BCOs were unresponsive. The majority of derivatives were placed substantially above Yoshida thresholds-a computational indicator of sensitivity. This study involved multiple reactions and reactants, such as Cubane-1,4-diyldimethanol (cas: 60462-27-3Recommanded Product: Cubane-1,4-diyldimethanol).

Cubane-1,4-diyldimethanol (cas: 60462-27-3) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Recommanded Product: Cubane-1,4-diyldimethanol

Novel 1,4-disubstituted cubane derivatives have been designed and selected ones have been successfully synthesized and characterized by various anal. and spectroscopic techniques, including single-crystal X-ray anal. A detailed computational study at B3LYP/6-311++G(d,p) level of theory revealed that all newly designed 1,4-disubstituted cubane derivatives possess higher densities, higher d.-specific impulse and superior ballistic properties when compared to conventional fuels, for example, RP-1. These compounds also exhibit acceptable kinetic and thermodn. stabilities which were evaluated in terms of their HOMO-LUMO energy gap and bond dissociation energies, resp., and are superior to TEX and many other compounds containing explosophoric groups. These results provide novel insights into the possible application of cubane-based energetic materials.

The preparation and fate of cubylcarbinyl radicals was written by Eaton, Philip E.; Yip, Yu Chi. And the article was included in Journal of the American Chemical Society on September 25,1991.Application of 60462-27-3 The following contents are mentioned in the article:

The cubylcarbinyl radical was generated from cubylcarbinyl bromide and from the N-hydroxy-2-pyridinethione ester of cubylacetic acid under various conditions favoring hydrogen-atom transfer to the radical. Only when selenophenol in high concentration is used as the hydrogen donor is any methylcubane formed. Otherwise the cubylcarbinyl radical rearranges. A mechanistic scheme accounting for their formation is presented; sequential σ-bond breaking occurs regioselectively, favoring processes in which there is good overlap between the radical orbital and that of the breaking bond. The rate constant for ring cleavage of cubylcarbinyl radical was calculated to be >2 × 1010 s-1, substantially greater than that of any radical derived to date from a saturated hydrocarbon system. This study involved multiple reactions and reactants, such as Cubane-1,4-diyldimethanol (cas: 60462-27-3Application of 60462-27-3).

And the article was included in Proceedings of the National Academy of Sciences of the United States of America on August 24,2010.Application In Synthesis of Cubane-1,4-diyldimethanol The following contents are mentioned in the article:

Rotary biomol. machines rely on highly sym. supramol. structures with rotating units that operate within a densely packed frame of reference, stator, embedded within relatively rigid membranes. The most notable examples are the enzyme FoF1 ATP synthase and the bacterial flagellum, which undergo rotation in steps determined by the symmetries of their rotators and rotating units. Speculating that a precise control of rotational dynamics in rigid environments will be essential for the development of artificial mol. machines, we analyzed the relation between rotational symmetry order and equilibrium rotational dynamics in a set of crystalline mol. gyroscopes with rotators having axial symmetry that ranges from two- to fivefold. The site exchange frequency for these mols. in their closely related crystals at ambient temperature varies by several orders of magnitude, up to ca. 4.46 × 108 s-1. This study involved multiple reactions and reactants, such as Cubane-1,4-diyldimethanol (cas: 60462-27-3Application In Synthesis of Cubane-1,4-diyldimethanol).
