Catalytic Cross-Coupling of Secondary Alcohols
Journal of the American Chemical Society, 2019 Herein, an unprecedented ruthenium(II) catalyzed direct cross-coupling of two different secondary alcohols to β-disubstituted ketones is reported. Cyclic, acylic, symmetrical, and unsymmetrical secondary alcohols are selectively coupled with aromatic benzylic secondary alcohols to provide ketone products.

Direct Amination of Secondary Alcohols Using Ammonia
Angewandte Chemie - International Edition, 2010 Hydrogen shuttle: For the first time secondary alcohols and ammonia can be directly converted into primary amines with a selectivity of up to 99¿% by using a simple ruthenium/phosphine catalyst (see scheme; R1, R2= alkyl, aryl, alkenyl; M=[Ru3(CO)12]; and L=phosphine ligand).

Tuning Ethanol Upgrading toward Primary or Secondary Alcohols by Homogeneous Catalysis
ACS Catalysis, 2023 Ethanol is one of the most promising renewable resources for producing key industrial commodities. Herein, we present the direct conversion of ethanol to either primary or secondary alcohols, or to hydrocarbons, using ruthenium PNP pincer complexes ...

α‐Alkylation of Ketones with Secondary Alcohols Catalyzed by Well‐Defined Cp*CoIII‐Complexes
ChemSusChem, 2019 International audienceAlthough α-alkylation of ketones with primary alcohols by transition-metal catalysis is well-known, the same process with secondary alcohols is arduous and complicated by self-condensation. Herein a well-defined, high-valence cobalt(

Secondary alcohol dehydrogenase
Biochimica et Biophysica Acta, 1962Abstract Secondary alcohol dehydrogenase, purified from a species of Pseudomonas , is specific for the DPN-linked oxidation of secondary alcohols and the DPNH-linked reduction of ketones; substrates include isopropanol, cyclohexanol and acetone.

Controlled racemization of enantiopure phenyl-ring-containing secondary alcohols is achieved in this study using W110A secondary alcohol dehydrogenase from Thermoanaerobacter ethanolicus (W110A TeSADH) and in the presence of the reduced and oxidized forms of its cofactor nicotinamide-adenine dinucleotide.

Mechanism of oxidation of secondary alcohols by bromine—oxidation of bicyclic secondary alcohols
Proceedings of the Indian Academy of Sciences - Section A, 1968The kinetics of the bromine oxidation of borneol, isoborneol,α-norborneol andβ-norborneol have been investigated in order to find out whether the oxidation is sensitive to the configuration of the alcohol. There is a definite and considerable variation in rate which is shown to arise from stereochemical consequences.

Enantiodivergent conversion of chiral secondary alcohols into tertiary alcohols
Nature, 2008From receptors in the nose to supramolecular biopolymers, nature shows a remarkable degree of specificity in the recognition of chiral molecules, resulting in the mirror image arrangements of the two forms eliciting quite different biological responses. It is thus critically important that during a chemical synthesis of chiral molecules only one of the

Alcoholic patients with secondary depression
American Journal of Psychiatry, 1983This study of alcoholic patients with and without secondary depression showed that the two groups were almost identical in demographic characteristics, early-life antisocial problems, quantity and frequency of drinking, and family history of affective disorder.
