| Abstract: | Di-μ-chlorobis(2-methyl-2-methoxy-3-t-butylthiopropyl)dipalladium(II) reacted with bis(1,3-diphenyl-2-imidazolidinylidene) to afford a new chlorobridged carbene complex {PdCl(did)}2] (did 1,3-diphenyl-2-imidazolidinyl-idenato,2-C,2′-C) in 46.2% yield, which has a cyclopalladated chelate structure involving a Pd—carbene and a Pd—aryl bond; new carbene complexes, {PdBr(did)}2], {Pd(CH3COO)(did)}2], Pd(acac)(did)], and PdCl(did)Q] (Q 4-MePy, POCHMe2]3) were also prepared from {PdCl(did)}2]. |
