Abstract

Solvent-free room temperature synthesis of tert-butyl peresters was achieved via copper-catalyzed oxidative-coupling of benzyl cyanides with tert-butyl hydroperoxide in short reaction times. Various derivatives of tert-butyl peresters were synthesized by this pathway in good to excellent yields. Further investigation revealed that the above-mentioned protocol is effective for the synthesis of benzoic acid derivatives when the reaction is conducted at 80?°C, under the same reaction conditions.
