1-Iodo-polyfluoroalkanes from polyfluoroalkoxy trimethylsilanes and iodochloro triphenylphosphorane
摘要:
Polyfluoroalkoxy trimethylsilanes R(f)CH(2)OSi(CH3)(3) (from the alcohols R(f)CH(2)OH and HMDS), react with Ph(3)PICl (from ICl and Ph(3)P) eliminating (CH3)(3)SiCl. Pyrolysis or the residues gives Ph(3)PO and pure iodides R(f)CH(2).
