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.

Ruthenium-Catalyzed Self-Coupling of Secondary Alcohols
The Journal of Organic Chemistry, 2023A 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.

Manganese‐Catalyzed Chemoselective Coupling of Secondary Alcohols, Primary Alcohols and Methanol
Angewandte Chemie, 2023AbstractHerein, we report a manganese‐catalyzed three‐component coupling of secondary alcohols, primary alcohols and methanol for the synthesis of β,β‐methylated/alkylated secondary alcohols. Using our method, a series of 1‐arylethanol, benzyl alcohol derivatives, and methanol undergo sequential coupling efficiently to construct assembled alcohols with

Severe thrombocytopenia secondary to alcohol use
Postgraduate Medicine, 1991Thrombocytopenia 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.

Xerophthalmia secondary to alcohol-induced malnutrition
Optometry - Journal of the American Optometric Association, 2006Xerophthalmia 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),

Oxidation of secondary ?-silicoacetylenic alcohols
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19691. 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.

Primary and Secondary Alcoholic Women
Social Casework, 1988Little attention has been given to the complex issues regarding assessment and treatment of primary and secondary alcoholic women. The author differentiates between these two groups, discusses clinical and psychosocial characteristics of each, and provides assessment and treatment strategies.

Alcohol Use and Abuse Secondary to Anxiety
Psychiatric Clinics of North America, 1990The 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.

Aetiology of Secondary Depression in Male Alcoholics
British Journal of Psychiatry, 1996BackgroundSecondary 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 ...
