Abstract
- La sulfonation de diphosphines de type-1,2, 1–3 et 1–4 (dppe, dppp, dppb) est ttudite. II est montre que la sulfonation est plus rapide pour les diphosphines-1,4 que pour les diphosphines-1,3 et 1,2. Les conditions permettant d'acceder a la tetrasulfonation sont precisees, ainsi que celles conduisant a un melange riche en phosphees disulfoees. Cette etude a ete etendue aux diphosphines chirales (Cyclobutanediop. BDPP, Chiraphos). The sulfonation of 1,2, -1,3 and -1,4 diphosphines (dppe, dppp, dppb) is studied. It is shown that the sulfonation is faster for 1,4-diphosphines than for -1,3 and -1,2 diphosphines. The conditions affording the tetrasulfonation are described, and also those allowing the obtention of a mixture containing large amounts of disulfonated diphosphines. This study is extended to chiral diphosphines (Cyclobutanediop, BDPP, Chiraphos).
