tert-Butyl hydroperoxide Structural Picture

What is tert-Butyl hydroperoxide?

Description

tert-Butyl hydroperoxide (TBHP) is an organic peroxide widely used in a variety of oxidation processes.

The Uses of tert-Butyl hydroperoxide

tert-Butyl hydroperoxide is used as an initiator for radical polymerization and in various oxidation process such as sharpless epoxidation. It is involved in osmium catalyzed vicinal hydroxylation of olefins under alkaline conditions. Furthermore, it is used in catalytic asymmetric oxidation of sulfides to sulfoxides using binaphthol as a chiral auxiliary and in the oxidation of dibenzothiophenes. It plays an important role for the introduction of peroxy groups in organic synthesis.
