The reaction of N-dichlorophosphoryl-P-trichlorophosphazene with alkyl grignard reagents

The reactions of N-dichlorophosphoryl-P-trichlorophosphazene Cl3P=N-P(O)Cl2 (1) with benzylmagnesium bromide, 2-phenylethylmagnesium bromide, trimethylsilylmethylmagnesium chloride, n-butylmagnesium bromide, cyclohexylmagnesium bromide, cyclopentylmagnesium bromide, tert-butylmagnesium bromide, iso-propylmagnesium bromide, and ethylmagnesium bromide were studied. Tri- and pentaalkyl phosphazenes were obtained in very poor yield from trimethylsilylmethylmagnesium chloride and cyclohexylmagnesium bromide, respectively. Trialkylphosphoryl compounds formed from benzyl-, 2-phenylethyl-, and n-butylmagnesium bromide. No phosphorus compound could be isolated from the reaction of 1 with t-butyl-, cyclopentyl-, iso-propyl-, and ethylmagnesium bromide.
