  Unexpected Rearrangement of 4-Chloro-2-butenylphosphinidene to 1-Chloro-2-vinylphosphirane in the Coordination Sphere of Tungsten

  摘要：

  The complex (4-chloro-2-butenylphosphinidene)pentacarbonyltungsten, as generated from the appropriate 7-phosphanorbornadiene complex at 58 degrees C in the presence of copper(1) chloride as a catalyst, readily rearranges to give the stable 1-chloro-2-vinylphosphirane complex. According to DFT calculations on similar Cr(CO)(5) complexes, a concerted six-electron (sigma C-Cl bond, P lone pair, and pi C=C double bond), five-center mechanism could be involved with a low energy barrier of 4.8 kcal mol(-1) in the chromium series.
