Method of producing phosphoranimines by reacting chlorophosphoranes with hexaalkyldisilazanes

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing chlorophosphoranimines of general formula R2(Cl)P=NSiR′3 and can be used in chemical industry. Method of producing chlorophosphoranimines general formula R2(Cl)P=NSiR′3 comprises reacting chlorophosphorane of general formula R2PCl3, where R is a chloro, alkyl, aryl, alkoxy or aryloxy group, with silazane and is characterised by that starting silazane used is hexaalkyl disilazane of general formula HN(SiR′3)2, dissolved in a chlorohydrocarbon, chlorophosphorane is added in crystalline form, synthesis is carried out at a temperature of -60 to 0 °C with a gradual raise, and hexaalkyl disilazane is used in an amount of 1 to 1.33 mol per 1 mol chlorophosphorane.

EFFECT: novel efficient method of producing compounds of general formula R2(Cl)P=NSiR′3.
