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.

Comparison of antioxidants in primary and secondary oxidations

Journal of the Science of Food and Agriculture, 1966
AbstractThe relative efficacies of a number of antioxidants including mono‐ and bis‐phenols were compared in gel emulsion systems containing linoleate and β‐carotene and subjected to autoxidation and to oxidation by lipoxidase and haemoglobin. They were also tested in liquid emulsions against oxidation of linoleate and vitamin A by lipoxidase ...

Secondary products of lipid oxidation

Chemistry and Physics of Lipids, 1987
In the last decade, a multitude of secondary products have been identified from the radical and photosensitized oxidations of polyunsaturated lipids. These secondary products consist of oxygenated monomeric materials including epoxy-hydroperoxides, oxo-hydroperoxides, hydroperoxy epidioxides, dihydroperoxides, hydroperoxy bis-epidioxides, and ...

Photoinduced Oxidation of Secondary Alcohols Using 4-Benzoylpyridine as an Oxidant

Organic Letters, 2015
Photoinduced oxidation of secondary alcohols to ketones was achieved by utilizing an equimolar amount of 4-benzoylpyridine as an oxidant. This transformation proceeds at ambient temperature and exhibits high compatibility with polar functionalities including benzoyl, silyl, and methoxymethyl alcohol protecting groups as well as tosyloxy, bromo ...

Oxidation of secondary ?-silicoacetylenic alcohols

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1969
1. A study was made of the oxidation of secondary γ-silicoacetylenic alcohols using chromic anhydride in sulfuric acid, and also Beckmann's oxidizing mixture, and a method for the preparation ofa- silicoacetylenic ketones in up to 95% yield was proposed on the basis of this reaction. 2.

On the Tautomerism of Secondary Phosphane Oxides

European Journal of Organic Chemistry, 2010
Abstract The tautomeric behaviour of five secondary phosphane oxides (SPOs) with different electronic properties has been investigated by NMR and IR spectroscopy, density functional theory calculations and X‐ray structural analysis.

Improved methods for the oxidation of primary and secondary alcohols

Journal of the Chemical Society, Perkin Transactions 1, 1975
The two-stage procedure for the oxidation of secondary alcohol chloroformates by treatment with dimethyl sulphoxide and then with triethylamine has been much improved by the addition of an acid scavenger, conveniently 1,2-epoxypropane, in the first stage of the sequence.In agreement with mechanistic considerations, treatment of cholestanol, or of its ...
