(β‐Diketiminato)cadmium Bis(trimethylsilyl)amide: Facile Access to Low‐Coordinate Cadmium Complexes

Abstract

A new route to access low‐coordinate (β‐diketiminato)cadmium complexes has been developed. Treatment of [Cd(HMDS)2] with BDI‐H (HMDS = [N(SiMe3)2]; BDI = [{N(2,6‐iPr2C6H3)C(Me)}2CH]) forms [(BDI)Cd(HMDS)], which is a useful synthon for the generation of other low‐coordinate cadmium complexes such as anilido complex [(BDI)Cd(NH{N(2,6‐iPr2C6H3})(THF)], aryloxo complex [(BDI)Cd(O‐2,6‐tBu2C6H3)], as well as chloro complex [{(BDI)CdCl}2]. [(BDI)Cd(HMDS)] is extremely sensitive to hydrolysis, generating [{(BDI)Cd(OH)}2] upon exposure to “dry” tert‐butyl alcohol.
