Bis(trifluoromethyl)cadmium*glyme (glyme = dimethoxyethane), a New, Powerful Fluoroalkylating Agent and Low-temperature Source of Difluorocarbene

Article abstract of DOI:10.1039/c39800000671

The newly isolated reagent (CF3)2Cd*glyme readily exchanges ligands with, e.g., GeI4, SnI4, or PI3 to form the fully substituted compounds (CF3)4Ge, (CF3)4Sn, or (CF3)3P, within minutes at ambient temperature; reactions with acyl halides, like MeC(O)Br, form the acyl fluorides, like MeC(O)F, in excellent yields, 95percent, at -25 deg C and extrusion of CF2 at -25 deg C in this reaction is indicated by the formation of the expected difluorocyclopopane from tetramethylethylene in 53percent yield.
