Abstract
The newly isolated reagent (CF3)2Cd·glyme [glyme =(MeOCH2)2] 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, 95%, at –25 °C and extrusion of CF2 at –25 °C in this reaction in indicated by the formation of the expected difluorocyclopropane from tetramethyl ethylene in 53% yield.Keywords
