    The binuciear palladium(I) complex, [Pd2Cl2(μ-dppm)2] (dppm = bis(diphenylphosphino)methane), has been shown to react with bis(diethylamino)acetylene, Et2NC≡CNEt2, in methylene chloride solution to yield two isolable products, the known methylene-bridged complex, [Pd2Cl2(μ-CH2)(μ-dppm)2], and hexakis(diethylamino)benzene, C6(NEt2)6, both of which have been characterized crystallographically. The source of the bridging methylene group in [Pd2Cl2(μ-CH2)(μ-dppm)2] has been shown to be the methylene chloride solvent. A mechanism that accounts for the formation of the two isolable products is proposed. The complex, [Pd2Cl2(μdmpm)2] (dmpm = bis(dimethylphosphino)methane), was similarly found to react with Et2NC≡NEt2 in methylene chloride solution to yield [Pd2Cl2(μ-CH2)(μ-dmpm)2], which was identified spectroscopically. Key words: acetylene, palladium, cyclooligomerization, aminoacetylene, hexakis(diethylamino)benzene.

    双核(I)配合物[Pd2Cl2(μ-dppm)2](dppm = 双(二苯基膦基甲烷)已被证明可与双(二乙基基)乙炔Et2NC≡CNEt2在甲基氯溶液中反应,产生两种可分离的产物:已知的甲基桥联配合物[Pd2Cl2(μ-CH2)(μ-dppm)2]和六(二乙基基)苯,C6(NEt2)6,两者均已晶体学表征。[Pd2Cl2(μ- )(μ-dppm)2]中桥联甲基基团的来源被证明是甲基氯溶剂。提出了一种解释形成这两种可分离产物的机理。同样地,[Pd2Cl2(μdmpm)2](dmpm = 双(二甲基膦基)甲烷)也被发现可在甲基氯溶液中与Et2NC≡NEt2反应,生成[Pd2Cl2(μ- )(μ-dmpm)2],并经光谱鉴定。关键词:乙炔,环寡聚合,乙炔,六(二乙基基)苯。
