Oxidative Deprotection of Silylethers, Acetals and Ketals by Oxygen or Air in Presence of Manganese and Cobalt Salts of 4-Aminobenzoic Acid Supported on Silica Gel as Catalyst

Abstract

Oxidative deprotection of silylethers, acetals and ketals to their corresponding alcohols, aldehydes and ketones have been achieved using oxygen or air in the presence of cobalt and manganese salts of 4-aminobenzoic acid supported an silica gel as catalysts. Reactions are clean and catalysts can be recovered easily and reused repeatedly.
