Current understanding of the sigma-bond metathesis reactions of LnMR+R '-H -> LnMR '+R-H

The metathesis reactions of LnMR + R '-H -> LnMR ' + R-H are important fundamental reactions in organometallic chemistry and catalysis. In this article, we reviewed the current understanding of the reactions from a theoretical point of view. Selected examples of the reactions involved in catalysis were discussed.
