Well-defined indium(<scp>iii</scp>) N-heterocyclic carbene complexes with triflate ligands: Structural models for the In(OTf)₃catalyst

Abstract

Reaction of 1,3-dimesitylimidazolium chloride [IMesH]Cl with InMe3 results in (IMes)InMe2Cl, which on treatment with one equivalent of TMS-OTf affords (IMes)InMe2(OTf), which can be converted to the bistriflate complex (IMes)In(Me)(OTf)2 on addition of HOTf.
