Structure and reactivity studies of transition metals ligated by tBuSi3X (X = O, NH, N, S, and CC)

Abstract

Use of the ^tBu₃Si group can sterically protect O, N, S, and acetylide donors, enabling chemistry at low-coordinate transition metal centers. This article provides examples from these laboratories on the utilization of ^tBu₃SiO⁻, ^tBu₃SiNH⁻, ^tBu₃SiN²⁻, ^tBu₃SiS⁻ and ^tBu₃SiCC⁻ as ligands in exploratory synthesis and reactivity studies of transition metal complexes.
