Selective C-H bond electro-oxidation of benzylic acetates and alcohols to benzaldehydes

Org Biomol Chem. 2017 Dec 6;15(47):10010-10015. doi: 10.1039/c7ob02300f.

Abstract

A chemical oxidant-free and mediator-free, direct electro-oxidation of both benzylic alcohols and benzylic esters are reported. The scope of the reaction is explored as a function of both steric and electronic effects. Expansion of the scope to non-benzylic and heteroaryl substrates is investigated. Functionalisation of esters and alcohols selectively to the aldehyde oxidation level using a traceless electron approach is reported.
