Synthesis and Reactivity of a Pentacoordinated Thiolate-Based Imido-Alkylidene W(VI) Complexes

Abstract

Attempt to synthesize a bis-thiolate tungsten alkylidene catalysts with bulky arenethiolates unexpectedly yielded upon activation of DME a pentacoordinated complex of general formula [W(NAr)(CHCMe3)(SAr’)(κ2-O-CH2-CH2-OMe)], which is active towards self-metathesis of cis-4-nonene compared to the parent bis-benzenethiolate.
