Science of Synthesis

Phillips, A. J.; Love, C. E., Science of Synthesis, (2007) 20, 827.

The conversion of ketones (and aldehydes) into esters by reaction with peroxy species such as 3-chloroperoxybenzoic acid, hydrogen peroxide, or tert-butyl hydroperoxide is known as the Baeyer–Villiger oxidation (‌Scheme 1‌). The reaction is of substantial importance to synthesis and has been reviewed a number of times. The reader is directed to these reviews for specific information outside the context of this brief survey.[‌1‌–‌10‌]
