A new tert-butyl peresterssynthesis directly from aldehydes and TBHP was developed via Bu(4)NI-catalyzed aldehyde C-H oxidation. Mechanistic studies suggest that the protocol proceeds via a radical process. Combining the method with the Kharasch-Sosnovsky reaction offers a practical approach for the synthesis of allylic esters from simple aldehydes and alkenes via a two-step one-pot procedure.

A green and efficient methodology has been developed for the direct conversion of aryl aldehydes to the corresponding tert-butyl peresters. The reaction has been carried out in absence of any solvent and the sunlight is used as the green source of energy. In this reaction tetrabutylammonium iodide (TBAI) acts as the mild organo catalyst and tert-butyl hydroperoxide (TBHP) serve as the source of tert-butyl
