摘要：
Donor-free bis(trifluoromethyl)cadmium, (CF3)(2)Cd, has been obtained at -40 degrees C from diethylcadmium and CF3I in a quantitative yield. The Raman spectrum of (CF3)(2)Cd is reported. In the presence of non-coordinating solvents the highly reactive compound eliminates CF2 even below -5 degrees C. Its feasibility as a low temperature difluorocarbene source has been demonstrated by difluorocyclo-propenation reactions with some alkenes and alkynes as well as by insertion into metal-chlorine bonds. The NMR spectra of some CF2Cl- and CF3-containing arsanes are reported.
