Abstract

The newly isolated reagent (CF3) 2Cd· glyme [glyme=(MeOCH2) 2] readily exchanges ligands with, eg, 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 ...
