摘要： The invention concerns cationic complexes of Technetium-99m with bidentate ligands (L), including complexes having the formulae [Tc(NO) X L.sub.2 ].sup.+ and [Tc L.sub.3 ].sup.+, which are of interest as heart imaging agents. The ligands are characterized by having the formula Y.sub.2 QZQY.sub.2, where each Q is phosphorus or arsenic, Z is a 2 or 3 carbon atom linking group, and at least one of the groups Y and Z includes at least one --COC--ether group.

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(CR4R5R6)TQ2-A-(K,D)Ar(E,Z)-B-Q1(Ad)u(CR1R2R3)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.
