Oxidation of Benzylic Hydrocarbons with Benzeneseleninic Anhydride and Related Reactions

Barton, Derek H. R.,Hui, Raymond A. H. F.,Ley, Steven V.

, p. 2179 - 2186 (2007/10/02)

The use of benzeneseleninic anhydride as a new side-chain oxidant for a variety of aromatic and heteroaromatic hydrocarbons has been investigated.The oxidation normally proceeds well for simple substrates, neat or in chlorobenzene solution at 100-130 deg C.In examples where the aromatic rings are susceptible towards electrophilic attack selenated compounds are usually formed as the major by-products.
