Synthesis and characterization of a homogeneous and silica supported homoleptic cationic tungsten(vi) methyl complex: application in olefin metathesis

Abstract

A method for the synthesis of a homogeneous cationic tungsten(VI)pentamethyl complex [(WMe5)+(C6F5)3BMe] from neutral tungstenhexamethyl (WMe6) and a silica supported cationic tungstentetramethyl complex [([triple bond, length as m-dash]Si–O–)WMe4+ (C6F5)3BMe] from a neutral silica supported tungstenpentamethyl complex [([triple bond, length as m-dash]Si–O–)WMe5] is described. In both cases a direct demethylation using the B(C6F5)3 reagent was used. The aforesaid complexes were characterized by liquid or solid state NMR spectroscopy. Interestingly, the homogeneous cationic complex [(WMe5)+(C6F5)3BMe] shows moderate activity whereas the supported cationic complex [([triple bond, length as m-dash]Si–O–)WMe4+(C6F5)3BMe] exhibits good activity in olefin metathesis reactions.
