A New Method for the Deoxygenation of Secondary Alcohols

Journal of the Chemical Society, Perkin Transactions 1, 1975
On reaction with tributylstannane, O-cycloalkyl thiobenzoates and O-cycloalkyl S-methyl dithiocarbonates, derived from secondary alcohols, give good yields of the corresponding hydrocarbons. The mechanism of this planned reaction is radical in character and thus rearrangements common in carbocation reactions are avoided. The particular applicability of

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 ...

Severe thrombocytopenia secondary to alcohol use

Postgraduate Medicine, 1991
Thrombocytopenia in hospitalized alcoholics may be caused by splenomegaly, folate deficiency, and, most frequently, a direct toxic effect of alcohol on production, survival time, and function of platelets. Platelet count begins to rise after 2 to 5 days' abstinence from alcohol.

Alcohol Use and Abuse Secondary to Anxiety

Psychiatric Clinics of North America, 1990
The relationship between alcohol use and anxiety is complex. From a clinical standpoint, it is clear that psychiatrists caring for anxious patients must be aware of the possibility of secondary alcohol abuse. For the most part, anxiety disorders are highly treatable conditions, whereas alcoholism is less successfully treated.

Xerophthalmia secondary to alcohol-induced malnutrition

Optometry - Journal of the American Optometric Association, 2006
Xerophthalmia refers to the ocular manifestations associated with vitamin A deficiency. Vitamin A deficiency can be caused by numerous disorders, including alcohol-induced malnutrition. The ocular manifestations of xerophthalmia include conjunctival and corneal xerosis (drying), keratomalacia (corneal necrosis/ulceration), nyctalopia (night blindness),

The production of secondary amyl alcohols

Petroleum Chemistry U.S.S.R., 1962
Abstract 1. 1 . It has been shown to be possible to carry out a continuous process for the production of amylsulphuric acid from technical pentane-amylene fractions and 85% sulphuric acid in the liquid phase at a temperature of 45° a contact time of 10 rain, and a pressure of 10 atm.

Aetiology of Secondary Depression in Male Alcoholics

British Journal of Psychiatry, 1996
BackgroundSecondary depression is common among primary alcoholics. However, its aetiology is poorly understood.MethodForty men with primary alcoholism, abstinent for two weeks or more, with a secondary major depressive episode were compared with forty matched never-depressed primary alcoholic controls for risk factors for depression and recent life ...

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.

The cyclisation of secondary allenic alcohols

Journal of the Chemical Society, Chemical Communications, 1984
The silver-mediated cyclisation of secondary allenic alcohols is streoselective giving predominantly cis-2,6-disubstituted tetrahydropyrans; this methodology has been applied to the synthesis of the civet constituent (4).
