资源简介：
The complex (4-chloro-2-butenylphosphinidene)pentacarbonyltungsten, as generated from
the appropriate 7-phosphanorbornadiene complex at 58 °C in the presence of copper(I)
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
(σ C−Cl bond, P lone pair, and π CC double bond), five-center mechanism could be involved
with a low energy barrier of 4.8 kcal mol-1 in the chromium series.
