Title
Molybdenum oxo–peroxo complex: A very fast catalyst for oxidation and reduction of sulfur-based compounds
Abstract

We have evaluated the catalytic activity of a molybdenum(VI) oxo–peroxo complex through the oxidation and reduction of sulfur-based compounds. Arylalkyl, diaryl and dialkyl sulfides are selectively oxidized to corresponding sulfoxides, with tert-butyl hydroperoxide (TBHP), in the presence of MoO(O2)(phox)2 complex as catalyst. This molybdenum complex was also found to be an efficient catalyst for the deoxygenation of sulfoxides to sulfides with PPh3 in excellent yields and chemoselectivity.
