Carbonylation of [Pd(8-mq)(OCMe(2))(x)]ClO4 (8-mq = 8-quinolylmethyl-C,N) in CH2Cl2/Me(2)CO at low temperature gave [Pd(8-mq)(OClO3)(CO)]. Reactions of [Pd(8-mq)(OClO3)(CO)] with anionic (Cl-, Br-, I-) or neutral (SPPh(3), SPMe(2)Ph) nucleophiles in a 1:1 molar ratio resulted in the displacement of the weakly coordinated OClO3- group and the formation of the corresponding neutral [Pd(8-mq)(X)(CO)] (X = Cl, Br, I) or cationic [Pd(8-mq)(CO)L]ClO4 (L = SPPh(3), SPMe(2)Ph) carbonyl complexes. The cationic complexes, [Pd(8-mq)(CO)L]ClO4, were synthesized by the reaction of [Pd(8-mq)(OClO3)(SPPh(3))] or [Pd(8-mq)(mu-SPMe(2)Ph)](2)(ClO4)(2) with CO. The X-ray structure of a cationic palladium carbonyl derivative, [Pd(8-mq)(CO)(SPPh(3))]ClO4, is reported. (C) 1997 Elsevier Science Ltd.
