Preparation of ylides containing the bis(perfluoroalkanesulphonyl)methylene functionality
摘要:
Various ylides containing the bis(perfluoroalkanesulphonyl)methylene functionality, Y+--C(SO2Rf)2 (Y=C5H5N, Ph3P, SMe2) have been synthesized by the reaction of phenyliodonium bis(perfluoroalkanesulphonyl)methide with pyridine, triphenylphosphine and dimethyl sulphide in good yield.
