Post-Functionalization: A Useful Method for the Synthesis of Donor-Func­tionalized N-Heterocyclic Carbene–Transition-Metal Catalysts

Abstract

Functionalized N-heterocyclic carbene ligands are particularly useful and widely applied ligands in transition-metal chemistry and catalysis. In this article we introduce an emerging synthetic method for functionalized N-heterocyclic carbene ligands developed from the reactivity study on cyclometalated N-hetero­cyclic carbene compounds, namely postfunctionalization. The status quo of this method for the preparation of novel donor-functionalized N-heterocyclic carbene complexes and their application in catalysis are discussed.

Key words

complexes - hydrosilylation - metallacycles - silane - transition metals

Silyl-substituted NHC ligands could be synthesized by the conventional synthetic method. But the silyl groups on these NHC ligands only function as innocent substituents, rather than chelating donors. For examples, see:
