On February 21, 2020, Jana, Akash; Das, Kuhali; Kundu, Abhishek; Thorve, Pradip Ramdas; Adhikari, Debashis; Maji, Biplab published an article.Electric Literature of 111-29-5 The title of the article was A Phosphine-Free Manganese Catalyst Enables Stereoselective Synthesis of (1 + n)-Membered Cycloalkanes from Methyl Ketones and 1,n-Diols. And the article contained the following:

Herein, we report the stereoselective synthesis of (1 + n)-membered cycloalkane from Me ketone and 1,n-diol. A manganese(I) complex bearing a phosphine-free ligand catalyzed the reaction, which involved the formation of two C-C bonds via a sequence of intermol.- and intramol.-borrowing hydrogenation reactions. It produces 2 mol of water as the sole byproduct, making the process atom economical and environmentally benign. Multisubstituted cycloalkanes were obtained in good to excellent yields with very high selectivities. A thorough mechanistic anal. by high-level DFT computation rationalizes the choice of the pincer and establishes the role of hemilability of the ligand for this efficient transformation. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Electric Literature of 111-29-5

Bains, Amreen K.; Kundu, Abhishek; Maiti, Debabrata; Adhikari, Debashis published an article in 2021, the title of the article was Ligand-redox assisted nickel catalysis toward stereoselective synthesis of (n+1)-membered cycloalkanes from 1,n-diols with methyl ketones.Computed Properties of 111-29-5 And the article contains the following content:

A well-defined, bench-stable nickel catalyst was presented here, that can facilitate double alkylation of a Me ketone to realize a wide variety of cycloalkanes. The performance of the catalyst depends on the ligand redox process comprising an azo-hydrazo couple. The source of the bis electrophile in this double alkylation was a 1,n-diol, so that (n+1)-membered cycloalkanes can be furnished in a stereoselective manner. The reaction followed a cascade of dehydrogenation/hydrogenation reactions and adopted a borrowing hydrogen (BH) method. A thorough mechanistic anal. including the interception of key radical intermediates and DFT calculations supported the ligand radical-mediated dehydrogenation and hydrogenation reactions, which is quite rare in BH chem. In particular, this radical-promoted hydrogenation was distinctly different from conventional hydrogenations involving a metal hydride and complementary to the ubiquitous two-electron driven dehydrogenation/hydrogenation reactions. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Computed Properties of 111-29-5

Monroe, Bruce M. published an article in 1977, the title of the article was Quenching of singlet oxygen by aliphatic amines.Synthetic Route of 2160-93-2 And the article contains the following content:

Rate constants for the quenching of singlet O (1O2) for 22 aliphatic amines were measured by following inhibition of the self-sensitized photooxidation of rubrene in CHCl3. A correlation of quenching rate with amine ionization potential was found for amines with unbranched alkyl groups. However, substitution of the C α to the N reduces the quenching rate from that predicted by the ionization potential, indicating that 1O2 quenching is sensitive to steric effects. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Synthetic Route of 2160-93-2

On July 14, 2020, Diroll, Benjamin T. published an article.Reference of 1-Decanethiol The title of the article was Ligand-Dependent Tuning of Interband and Intersubband Transitions of Colloidal CdSe Nanoplatelets. And the article contained the following:

Although surface ligands of colloidal nanocrystals are known to adjust the absolute energy levels of valence and conduction bands of semiconductor nanocrystals, they typically have only minor influence on the band gap or effective masses. This changes in nanoplatelets. Ligand exchange of CdSe colloidal nanoplatelets induces large (up to 300 meV) bathochromic shifts of both interband and intersubband transitions. Here, three families of ligands-halides, thiolates, and phosphonates-are used to tune interband transitions, reflecting electron and hole confinement, across visible wavelengths and intersubband transitions, reflecting electron confinement, across the near-IR spectral window. Careful examination shows that delocalization from expansion of the nanoplatelet short axis, which was reported previously, cannot alone explain observed red shifts. Instead, comparison of intersubband, interband, and hole energy levels shows that ligand head group chem. confers specific, idiosyncratic adjustments of the contribution of conduction and valence bands to the observed bathochromic shifts. Phosphonate ligands show the largest band gap reductions but the smallest red shift of intersubband transition energies; halide-exchanged samples displayed smaller reductions in band gap but large red shifts of intersubband transitions; thiolates fall in between. A related specificity is observed in hole states, which implicates ligand-responsive valence band curvature as an addnl. contribution driving optical changes. For nanoplatelets, surface ligand chem. offers not only a tool to adjust the absolute energy level of conduction and valence bands but also an alternative route to preferential electron or hole band engineering that is normally achieved with inorganic shells. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Reference of 1-Decanethiol
