A PHOSPHA-ADAMANTANE (S) CATALYTIC SYSTEM

摘要

A catalyst system capable of catalysing the carbonylation of an olefinally unsaturated compound is described. The 5 catalyst system is obtainable by combining: (a) a metal of Group VIB or Group VIII B or a compound thereof; and (b) a bidentate phosphine of general formula (I) Ad) s (CR<4>R<5>R<6>) T Q<2>-A- (K, D) Ar (E, Z) -B-Q<1> (Ad) u (CR<1>R<2>R<3>) v. Ad represents an optionally substituted adamantyl radical bonded to the phosphorous atom via any one of its tertiary carbon atoms. A method of production of the catalyst is also illustrated.
