Alcohols by chromium

Scheme 6.29 Oxidation of alcohols by chromium trioxide supported on premoistened alumina. Scheme 6.29 Oxidation of alcohols by chromium trioxide supported on premoistened alumina.
The probable mechanism of oxidation of alcohols by chromium (VI) species involves the formation of chromate esters and their subsequent decomposition to ketones (57). As a rule, in the absence of competing side reactions, the more hindered alcohols react faster than the less hindered compounds. It has also been... [Pg.20]

The chromium trioxide-pyridine complex is a highly selective oxidant for alcoholic groups [28]. A mechanism similar to that discussed above seems possible, the selectivity being due to lowered reactivity of chromium trioxide in the pyridine complex. The remarkably smooth and selective oxidation of alcohols by chromium trioxide-sulphuric acid (Jones reagent) in acetone solution [2g] has not been explained. [Pg.267]
