Abiko, Yohei published the artcileThermoresponsive core-shell nanoparticles with cross-linked π-conjugate core based on amphiphilic block copolymers by RAFT polymerization and palladium-catalyzed coupling reactions, Category: alcohols-buliding-blocks, the publication is Polymer (2014), 55(23), 6025-6035, database is CAplus.

Well-defined amphiphilic block copolymers composed of S-vinyl sulfides and N-iso-Pr acrylamide (NIPAM) were synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization Thermoresponsive core-shell nanoparticles with crosslinked π-conjugate cores were obtained by in situ crosslinking reactions between 4-bromophenyl moieties in the block copolymers and diboronic acids or a diamine compound in the presence of a palladium catalyst following micelle formation in ethanol/H₂O or ethanol. We initially investigated RAFT polymerization of two S-vinyl sulfide derivatives, namely Ph vinyl sulfide (PVS) and 4-bromophenyl vinyl sulfide (BPVS), using a dithiocarbamate-type chain transfer agent (CTA). Then, RAFT polymerization of NIPAM using poly(S-vinyl sulfide) macro-CTAs was conducted to synthesize the amphiphilic block copolymers. Suzuki and Buchwald-Hartwig coupling reactions were found to be effective in the preparation of core-shell nanoparticles with thermoresponsive shells and crosslinked optoelectronic cores. The resulting nanoparticles showed characteristic thermoresponsive properties, as confirmed by turbidity and dynamic light scattering measurements. Stable and uniform core crosslinked nanoparticles were successfully prepared by the in situ palladium-catalyzed coupling reactions, and the optoelectronic and thermoresponsive properties of the nanoparticles could be tuned depending on the nature of the difunctional coupling agents, reaction conditions, and comonomer composition of the block copolymers.

Hasegawa, Minoru published the artcileSynthesis and properties of antimony compounds of the type Sb(OSiR₃)₃, Product Details of C9H22OSi, the publication is Nippon Kagaku Kaishi (1995), 550-6, database is CAplus.

Novel organoantimony compounds Sb(OSiR₃)₃ [1, R¹ = R² = R³ = Me; 2, R¹ = R² = R³ = Pr; 3, R¹ = R² = R³ = i-Pr;4, R¹ = R² = Me, R³ = t-Bu; 5, R¹ = R² = R³ = Ph] were prepared in 41-81% yields by the reaction of SbCl₃ with NaOSiR₃ (1:3 mol ratio) in toluene. These compounds were characterized by IR, ¹H, ¹³C, and ²⁹Si-NMR, and MS spectroscopy. According to MS and NMR spectral data, each compound appears to be a monomer. They are subject to hydrolysis at room temperature Thus, treatment of 1–4 with a large excess of H₂O under slightly forced conditions gave the corresponding silanols and Sb trioxides. IR and XPD data suggest the resulting Sb trioxides are two polymorphs; the 1st polymorph is senarmontite obtained by hydrolysis of 1–4 in H₂O/MeOH and the 2nd polymorph is valentinite given by hydrolysis of 3 and 4 in H₂O/acetone.

The reactions of aliphatic fluoro-alcs. with chlorodifluoromethane (CHClF₂) at atm. pressure were examined In the reaction of CF₃CF₂CH₂OH, the difluoromethylated ether was obtained in moderate yield by using ethers such as 1,4-dioxane, diglyme, and THF, or their mixtures with water as a reaction solvent. While acetal and orthoformate were also produced, the selectivity of the difluoromethylated ether could be improved by adding water to the reaction. The effect of water could be explained by the reaction mechanism.

Mizukado, Junji published the artcileInsertion reactions of difluorocarbene generated by pyrolysis of hexafluoropropene oxide to OH bond, Application In Synthesis of 2240-88-2, the publication is Journal of Fluorine Chemistry (2005), 126(3), 365-369, database is CAplus.

ROCHF₂-type fluorinated ethers were synthesized by the reaction of hexafluoropropene oxide (HFPO) with alc. or phenol. In this reaction, although the insertion reaction of difluorocarbene to O-H bond and the nucleophilic attack of alc. or phenol to HFPO were competition, the insertion reaction proceeded predominantly to give fluorinated ether in the case of low nucleophilic alc. or phenol. In addition, high reaction pressure is advantageous to the selectivity of the fluorinated ethers in the reaction of HFPO with (CF₃)₂CHOH or C₆F₅OH.

Pramanik, Milan published the artcileSulfur···oxygen interaction-controlled (Z)-selective anti-Markovnikov vinyl sulfides, Category: alcohols-buliding-blocks, the publication is Chemical Communications (Cambridge, United Kingdom) (2021), 57(46), 5698-5701, database is CAplus and MEDLINE.

The sulfur oxygen (S···O) interaction was used herein to obtain (Z)-selective anti-Markovnikov vinyl sulfides from the addition of thiyl radicals to N-aryl propynamides. DFT calculations predicted that S···O interaction originated from the delocalization of the lone-pair of the carbonyl oxygen to the adjacent σ^* orbital of the S atom of C-S.

Pramanik, Milan published the artcilet-BuOLi-promoted terminal alkyne functionalizations by aliphatic thiols and alcohols, SDS of cas: 4410-99-5, the publication is Organic & Biomolecular Chemistry (2022), 20(13), 2671-2680, database is CAplus and MEDLINE.

Selective addition of aliphatic thiols or alcs. R¹XH (X = O, R¹ = Me, Et, F₃CCH₂, n-decyl, etc.; X = S, R¹ = i-Bu, PhCH₂, n-dodecyl, 2-furylmethyl, etc.) to N-aryl propiolamides HCCC(O)NHR² (R² = Ph, 2-MeC₆H₄, 3,4-Cl₂C₆H₃, etc.) using lithium tert-butoxide in ethanol as a promoter is described. Mechanistically, it was shown that the reaction proceeds through the generation of a thiyl radical intermediate, and the amide group in N-phenylpropiolamide helps in the activation of the alkyne, which led to thioacetalization via the formation of a (Z)-selective anti-Markovnikov vinyl sulfide. The (Z)-selectivity during the formation of vinyl sulfides was controlled by an intramol. sulfur···oxygen interaction.

In this paper, we report the construction of hydrogen bonded supramol. assemblies of salt obtained from novel nitrogen rich C₃-sym. star-shaped triaminoguanidine-pyrrole conjugate and various carboxylic acids. Different types of supramol. assembly were achieved by using a variety of carboxylate anions. Formation of all compounds were confirmed by single crystal anal. The hydrogen bonded three-dimensional supramol. network assemblies (1-6) are harvested by utilizing traditional N-H···O, O-H···O, and weak C-H···π interactions. Among all salts, heterosynthons R¹₂(10) containing traditional N-H···O interactions are commonly observed The thermal stability of salt 1-6 has been examined by thermogravimetric anal. (TGA).
