Efficient uptake of dimethyl sulfoxide by the desoxomolybdenum(iv) dithiolate complex containing bulky hydrophobic groups

Abstract

A desoxomolybdenum(IV) complex containing bulky hydrophobic groups and NH⋯S hydrogen bonds, (Et₄N)[Mo^IV(OSi^tBuPh₂)(1,2-S₂-3,6-{(4-^tBuC₆H₄)₃CCONH}₂C₆H₂)₂], was synthesized. This complex promotes the oxygen-atom-transfer (OAT) reaction of DMSO by efficient uptake of the substrate into the active center. The clean OAT reaction of Me₃NO is also achieved.
