Donor-free bis(trifluoromethyl) cadmium, (CF 3) 2Cd: a readily available low-temperature difluorocarbene source

Donor-free bis(trifluoromethyl)cadmium, (CF 3) 2Cd, has been obtained at −40 °C from diethylcadmium and CF 3I in a quantitative yield. The Raman spectrum of (CF 3) 2Cd is reported. In the presence of non-coordinating solvents the highly reactive compound eliminates CF 2 even below −5°C. Its feasibil...

Description
Summary:Donor-free bis(trifluoromethyl)cadmium, (CF 3) 2Cd, has been obtained at −40 °C from diethylcadmium and CF 3I in a quantitative yield. The Raman spectrum of (CF 3) 2Cd is reported. In the presence of non-coordinating solvents the highly reactive compound eliminates CF 2 even below −5°C. Its feasibility as a low temperature difluorocarbene source has been demonstrated by difluorocyclopropenation reactions with some alkenes and alkynes as well as by insertion into metal-chlorine bonds. The NMR spectra of some CF 2Cl- and CF 3-containing arsanes are reported.
