Organometallic chemistry

a concerted four-center exchange of sigma bonds at a metal that cannot change oxidation state, typical of early transition metal and lanthanide alkyls.

In organometallic chemistry, sigma-bond metathesis refers to a concerted four-center exchange of sigma bonds at a metal that cannot change oxidation state, typical of early transition metal and lanthanide alkyls. This meaning comes from Thompson (1987) in Journal of the American Chemical Society.[1]
