Abstract:
The binuciear palladium(I) complex, [Pd 2 Cl 2 (μ-dppm) 2 ] (dppm = bis(diphenylphosphino)methane), has been shown to react with bis(diethylamino)acetylene, Et 2 NC≡CNEt 2 , in methylene chloride solution to yield two isolable products, the known methylene-bridged complex, [Pd 2 Cl 2 (μ-CH 2 )(μ-dppm) 2 ], and hexakis(diethylamino)benzene, C 6 (NEt 2 ) 6 , both of which have been characterized crystallographically. The source of the bridging methylene group in [Pd 2 Cl 2 (μ-CH 2 )(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, [Pd 2 Cl 2 (μdmpm) 2 ] (dmpm = bis(dimethylphosphino)methane), was similarly found to react with Et 2 NC≡NEt 2 in methylene chloride solution to yield [Pd 2 Cl 2 (μ-CH 2 )(μ-dmpm) 2 ], which was identified spectroscopically. Key words: acetylene, palladium, cyclooligomerization, aminoacetylene, hexakis(diethylamino)benzene.
