Description

General description

Oxidation of phenols by benzeneseleninic acid anhydride yields ortho-quinones. Benzeneseleninic anhydride acts as a mild oxidant for the conversion of benzylic hydrocarbons into aldehydes or ketones.

Application

Benzeneseleninic acid anhydride was used to oxidize hydrazines to afford azo-compounds.

Chemical & pharmaceutical bulletin, 52(8), 1009-1012 (2004-08-12)

Benzeneseleninic anhydride in the presence of tert-butyl hydroperoxide in chlorobenzene at about 70 degrees C is an effective oxidizing agent for the selective oxidation of alcohols at the benzylic position.

A facile one-step synthesis of delta 1,4-3-keto bile acid esters by iodoxybenzene and benzeneselenic anhydride.

T Iida et al.

Journal of lipid research, 29(8), 1097-1101 (1988-08-01)

A facile one-step conversion of stereoisomeric methyl 3-hydroxycholanoates to 1,4-dien-3-one, by treatment in boiling toluene with iodoxybenzene catalyzed by benzeneselenic anhydride, is described. The direct oxidation-dehydrogenation at C-3 is applicable to other cholanoates (hyodeoxycholic, chenodeoxycholic, ursodeoxycholic, deoxycholic, and cholic) when
