Full title: Reactions of dimeric palladium(I) complexes with sulfur-substituted acetylenes: 1,2-heteroatomic shift reactions versus adduct formation. X-ray crystal structures of [Pd2Cl2(μ-dppm)2(μ-CH 3SCCSCH3)]·CH2Cl2, [Pd2Cl2(μ-dmpm)2(μ-CH 3SCCSCH3)], and [Pd2Cl2(μ-dppm)2(μ-σ-C=C(CH 3)(SCH3))]. The palladium(I) complexes [Pd2Cl2(μ-dppm)2] (dppm = bis(diphenylphosphino)methane) and [Pd2Cl2(μ-dmpm)2] (dmpm = bis(dimethylphosphino)methane) have been shown to react with the symmetrical sulfur-substituted acetylene CH3SC≡CSCH3 to yield [Pd2Cl2(μ-dppm)2(μ-CH 3SCCSCH3)], 1, and [Pd2Cl2(μ-dmpm)2(μ-CH 3SCCSCH3)], 2. The acid-catalyzed reaction of the unsymmetrically substituted acetylene, CH3SC≡CCH3, with [Pd2Cl2(μ-dppm)2] led to the formation of the bridged vinylidene complex [Pd2Cl2(μ-dppm)2(μ-σ-C=C(CH 3)-(SCH3))], 3, via a formal 1,2-shift of the heteroatomic group. The structures of complexes 1·CH2Cl2, 2, and 3 have been determined by X-ray crystallography.
