摘要:
An improved synthesis of ferrocenyldimethylphosphine, FcPMe2, is limited only by the unreliable literature procedure for preparlng precursor dichloroferrocenylphosphine, FcPCl2. The latter compound yields a crystalline copper(I) iodide complex on reaction with lithium dimethylcuprate. Methanolysis of FcPCl2 yields unstable dimethyl ferrocenylphosphonite, FcP(OMe)2, which is converted to methyl ferrocenylphosphinite, FcPH(O)OMe, on heating or chromatography.
