The reaction of triorganyl(dimethylamino)silanes with surface-hydrated silicon dioxide has been studied. These silylatingagents are easy to prepare from the corresponding chloro or bromosilanes with dimethylamine. The resulting products are thermally stable and relatively volatile. Reaction with surface-hydrated silicon-dioxide preparations at 150–250°C for 170 h yields a dense grafted layer. However
A method of forming SiN bonds by dehydro-coupling of SiH and NH bonds in the presence of a nucleophilic catalyst is reported. The method is useful for the preparation of silylamines and silazanes and for crosslinking of organometallics polymers.
