资源简介：
Transient
terminal phosphinidene complexes [RP-W(CO)5] dimerize in
the presence of copper chloride, and the dimers react in situ with
triphenylphosphine–borane to give the disecondary diphosphine
complexes [RPH–PHR][W(CO)5]2. When R
= CH2CH2Cl, a cyclization takes place to give
the diphosphirane complex. A 1,2-diphospholane is obtained for R =
Ph by further reaction with 1,3-dibromopropane in the presence of
aqueous K2CO3.
