Polymer-bound alkyl diarylphosphinite catalyst compositions having the formula I: ##STR1## wherein the trivalent phosphorus is substituted by one alkoxy group and one aryl group and wherein the third bond of phosphorus is a P-C bond to a pendant aryl groups of the polymer matrix and wherein .circle.p --C.sub.6 H.sub.4 -- is a polymer matrix containing aromatic groups such as polystyrene cross-linked with divinylbenzene and wherein at least 1% of pendant aryl groups of the polymer matrix are bound to phosphorus and wherein Ar is substituted by electron-donating groups such as alkyl, alkoxy, and N,N-dialkylamino, are disclosed. Polymer-bound aryl dialkyl phosphonites having the formula II, .circle.p --C.sub.6 H.sub.4 --P(OR).sub.2 and polymer-bound diarylphosphinous chlorides having the formula .circle.p --C.sub.6 H.sub.4 --P--(Ar')--Cl are also disclosed. Processes for making the polymer-bound phosphinites, phosphonites and phosphinous chlorides are also disclosed.
本发明涉及一种具有I式的聚合物结合烷基二芳基膦酸酯催化剂组合物:
##STR1##
其中三价磷被一个烷氧基和一个芳基取代,磷的第三键是与聚合物基质的悬挂芳基之一形成的P-C键,其中.circle.p-C6H4-是含有芳香基团的聚合物基质,例如与二乙烯基苯交联的聚苯乙烯,并且聚合物基质的至少1%的悬挂芳基团与磷结合,其中Ar被电子供体基团如烷基,烷氧基和N,N-二烷基氨基取代。本发明还涉及具有式II的聚合物结合芳基二烷基膦酸酯:.circle.p-C6H4-P(OR)2和具有式.circle.p-C6H4-P-(Ar')-Cl的聚合物结合二芳基膦酸氯化物。本发明还涉及制备聚合物结合膦酸酯,膦酸酯和膦酸氯化物的方法。
