Abstract

The rates of self‐condensation of a series of silylamines of the type R~3~SiNH~2~ to form the corresponding disilazanes, (R~3~Si)~2~NH have been measured. The nature of the R groups attached to the silicon atom of the silylamine appreciably affects the rate of condensation. The addition of acid catalyst results in an increase in reaction rate. The observed second‐order kinetics indicate a bimolecular type mechanism.
