General Synthesis of N-Alkylation of Amines with Secondary Alcohols via Hydrogen Autotransfer.

Organic Letters, 2019
Direct catalytic N-alkylation of amines with secondary alcohols via hydrogen autotransfer (HA) strategy is very challenging and has been scarcely reported, even under precious metal catalysis.

Anesthetic Potencies of Secondary Alcohol Enantiomers

Anesthesiology, 1987
The Meyer-Overton rule has been interpreted to mean that general anesthetics act at a nonpolar site, either in a lipid bilayer or a protein. Optical isomers, also called enantiomers, are pairs of compounds with the same molecular formula and functional groups, but which differ in the arrangement of the groups around an "asymmetric" carbon atom and in ...

Selective Ketone Formations via Cobalt-Catalyzed β-Alkylation of Secondary Alcohols with Primary Alcohols.

Organic Letters, 2019
A homogeneous cobalt-catalyzed β-alkylation of secondary alcohols with primary alcohols to selectively synthesize ketones via acceptorless dehydrogenative coupling is reported for the first time. Notably, this transformation is environmentally benign and

Iron-Catalyzed Ligand Free α-Alkylation of Methylene Ketones and β-Alkylation of Secondary Alcohols Using Primary Alcohols.

Journal of Organic Chemistry, 2019
Herein, we demonstrated a general and broadly applicable catalytic cross-coupling of methylene ketones and secondary alcohols with a series of primary alcohols to di-substituted branched ketones.

Ruthenium-Catalyzed Selective Hydrogenation of Epoxides to Secondary Alcohols.

Organic Letters, 2019
A ruthenium(II)-catalyzed highly selective Markovnikov hydrogenation of terminal epoxides to secondary alcohols is reported. Diverse substitutions on the aryl ring of styrene oxides are tolerated.

Ni-catalysed, domino synthesis of tertiary alcohols from secondary alcohols

Chem. Commun., 2012
The use of in situ generated (NHC)-Ni catalytic species (NHC = N-heterocyclic carbene) allows for the synthesis, in short reaction times, of a variety of tertiary alcohols from secondary alcohols through a domino oxidation-addition protocol.

Alcoholic patients with secondary depression

American Journal of Psychiatry, 1983
This 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.

C-Alkylation of Secondary Alcohols by Primary Alcohols through Manganese-Catalyzed Double Hydrogen Autotransfer.

ChemSusChem, 2018
A new Mn-catalyzed alkylation of secondary alcohols with non-activated alcohols is presented. The use of a stable and well-defined manganese pincer complex, stabilized by a PNN ligand, together with a catalytic amount of base enabled the conversion of ...

Mechanism of oxidation of secondary alcohols by bromine—oxidation of bicyclic secondary alcohols

Proceedings of the Indian Academy of Sciences - Section A, 1968
The 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.

Ruthenium-Catalyzed Self-Coupling of Secondary Alcohols

The Journal of Organic Chemistry, 2023
A simple catalytic method for self-coupling of secondary alcohols leading to the synthesis of β-branched ketones under mild conditions is reported. Well-defined ruthenium pincer complex catalyzed the reactions. Optimization studies revealed that sodium tert-butoxide is an appropriate base for this transformation.
