Synthesis and Reactivity of a Neutral, Three-Coordinate Platinum(II) Complex Featuring Terminal Amido Ligation

A crystallographically characterized three‐coordinate, formally 14 electron PtII complex 1 featuring terminal amido ligation is reported. Computational analysis revealed relatively weak π donation from the amide lone pair to platinum and supports a 14‐electron assignment for 1. Stoichiometric reacti...

Description
Summary:A crystallographically characterized three‐coordinate, formally 14 electron PtII complex 1 featuring terminal amido ligation is reported. Computational analysis revealed relatively weak π donation from the amide lone pair to platinum and supports a 14‐electron assignment for 1. Stoichiometric reactivity studies confirmed the viability of net OH and CH addition across, as well as isonitrile insertion into, the terminal platinum–amido linkage of 1. How low can you go? A formally 14 electron PtII complex featuring terminal amido ligation was isolated and characterized crystallographically (see scheme; 1‐Ad=1‐adamantyl). A combination of stoichiometric reactivity studies and computational analysis confirmed the viability of net OH and CH addition across, as well as isonitrile insertion into, the terminal platinum–amido linkage of this unusual low‐coordinate complex.
