  Preparation, structural characterization of 1,2-digermacyclobut-3-enes, and their palladium-catalyzed insertion of alkynes

  摘要：

  1.2-Diaermacyclobut-3-enes were prepared by the treatment of Z-alpha,beta-bis(chlorodialkylgermyl)ethenes with Na metal in boiling toluene and their structures were fully established by spectroscopic methods coupled with X-ray crystallography. In the presence of an appropriate catalyst, 1,2-digermacyclobut-3-enes reacted smoothly with alkynes to give the corresponding insertion products, 1,4-digermacyclohexa-2,5-dienes in moderate to good yields. Conventional complexes, such as [Pd(PPh3)(4)] and [Pt(PPh3)(4)], serve as efficient catalysts. The mechanism of the insertion reaction of alkynes into the germanium-germanium bond of 1.2-digermacyclobut-3-enes is discussed in terms of a key intermediate, a 1,4-digerma-2-buten-1,4-diylpalladium.

  4-diylplatinum(II) complexes were prepared by treatment of a (η-ethylene)(triphenylphosphine)platinum(0) complex with (Z)-α,β-bis(dialkylgermyl)styrenes, and their structures were determined by spectroscopic analysis coupled with X-ray diffraction methods. Thermolysis of 1,4-digerma-2-buten-1,4-diylplatinum(II) complexes afforded linear and cyclic trigermanes and a dinuclear platinum complex. The 1,4-digerma-2-buten-1
