METHOD OF PRODUCING PHOSPHORANIMINES BY REACTING CHLOROPHOSPHORANES WITH HEXAALKYLDISILAZANES Russian patent published in 2016 - IPC C07F9/535

Abstract RU 2586218 C1

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.
