The present application relates to a process for preparing a halogenated organophosphine, comprising reacting a primary or secondary organophosphine with a halogenating agent selected from (A) a compound of formula (I) : (HaI)3C-C(O)-X (I) wherein X is selected from alkyl, aryl, aralkyl, alkaryl, cycloalkyl, NR1R2, C(HaI)3, OR3, -O-C(O)-R3', or -Y-Z-Y-C(O)- C(Hal)3i R1 and R2 are each independently selected from hydrogen, alkyl, aryl, aralkyl, alkaryl, or cycloalkyl; R3 is selected from H, alkyl, aryl, aralkyl, alkaryl, cycloalkyl, or triorganosilyl; R3' is selected from C(HaI)3, alkyl, aryl, aralkyl, alkaryl, cycloalkyl; Y is independently selected from 0 or NH; Z is independently selected from alkylene, arylene, aralkylene, alkarylene, or cycloaky- lene; and Hal is selected from Cl or Br; or (B) a derivative of a polyol, polyamine or polyaminoalcohol comprising two or more hydroxyl and/or amino groups, in which a hydrogen atom in each of the hydroxyl and/or amino groups is replaced with a group -C(O)-C(HaI)3, wherein Hal is selected from Cl or Br.
La présente invention porte sur un procédé pour la fabrication d'une organophosphine halogénée, comprenant la réaction d'une organophosphine primaire ou secondaire avec un agent d'halogénation choisi parmi (A) un composé représenté par la formule (I) : (Hal)3C-C(O)-X (I) dans laquelle X est choisi parmi un groupe alkyle, aryle, aralkyle, alkaryle, cycloalkyle, NR1R2, C(Hal)3, OR3, -O-C(O)-R3' ou -Y-Z-Y-C(O)-C(Hal)3; R1 et R2 sont chacun indépendamment choisis parmi un atome dhydrogène, un groupe alkyle, aryle, aralkyle, alkaryle ou cycloalkyle; R3 est choisi parmi H, un groupe alkyle, aryle, aralkyle, alkaryle, cycloalkyle ou triorganosilyle; R3' est choisi parmi un groupe C(Hal)3, alkyle, aryle, aralkyle, alkaryle, cycloalkyle; Y est indépendamment choisi parmi O ou NH; Z est indépendamment choisi parmi un groupe alkylène, arylène, aralkylène, alkarylène ou cycloalkylène; et Hal est choisi parmi Cl ou Br; ou (B) un dérivé d'un polyol, d'une polyamine ou d'un polyaminoalcool comprenant deux ou plus de deux groupes hydroxyles et/ou amino, dans lequel un atome d'hydrogène de chacun des groupes hydroxyles et/ou amino est remplacé par un groupe -C(O)-C(Hal)3, où Hal est choisi parmi Cl ou Br.
