ABSTRACT:
There are prepared nitrogen containing alkoxysilanes of the formula (RO).sub.3-n (CH.sub.3).sub.n Si(CH.sub.2).sub.m NHCON.sub.3 in which R is an alkyl group having 1 to 3 carbon atoms, n is 0, 1 or 2 and m is 1, 2 or 3 by a process comprising dissolving in an inert solvent an isocyanate group containing silane of the formula (RO).sub.3-n (CH.sub.3).sub.n Si(CH.sub.2).sub.m N.dbd.C.dbd.O in which R, n and m are as defined above and reacting the silane with a water free hydrogen nitride or with hydrogen halide and an alkali metal-alkaline earth metal-, or ammonium azide at a temperature between 0.degree. C. and the boiling point of the inert solvent. The compounds are useful in making phosphinimines.
