Abstract

A new synthetic route providing access to the highly reactive intermediate [Cp*(CO)2WPW(CO)5] with a tungsten-phosphorus triple bond is presented (see scheme). The intermediate is formed by thermolysis of [Cp*P{W(CO)5}2] by Cp* migration from the phosphorus to give 5 coordination at the transition metal. Addition of other reactive molecules to solutions conatining the intermediate provides a simple approach to novel W/P-containing ligands.
