  描述：

  pentacarbonyl(1,1-dichloromethylisocyanide)chromium 在 三苯基膦 作用下， 以 乙醇 为溶剂， 生成 triphenylphosphine chromium pentacarbonyl 、 cis-(CO)4Cr(PPh3)2

  名称：

  Reaktionen am koordinierten Trichlormethylisocyanid

  摘要：

  Cr(CO)5CNCCl3 (3) reacts with phosphane (PPh3, PMe2Ph, PEt3) under aprotic conditions to give the Cr(CO)5-coordinated semiylidic isocyano(phosphoraneylidene)methylphosphoniumchlorides 4, 13. In the presence of (traces of) water, however, mainly (isocyano)methylphosphonium complexes 5, 10, 11 are formed. In a side reaction, 3 is reduced to give Cr(CO)5CNCHCl2 which becomes the main product when the reaction is carried out in alcohol, acetone, or in the presence of a carboxylic acid (e.g. (PhCOOH).

  日期：1992.9

  Pentacarbonyl(fluoromethyl isocyanide)chromium and pentacarbonyl(difluoromethyl isocyanide)chromium have been prepared. The vibrational spectroscopic data for the compounds indicate that these isocyanide ligands have a lower pi-acceptor/sigma-donor ratio than trifluoromethyl isocyanide.
