During the thermal decomposition of (CF3)2Cd and (CF3)2Zn complexes primarily difluorocarbene is eliminated.The formation of CF2 is unambiguously proved by matrix i.r. spectroscopy.Both (CF3)2Cd*D and (CF3)2Zn*D are excellent CF2 sources, which can easily be prepared and handled, and which undergo CF2 reactions even at low temperature.CF2 insertion was found during the reaction of (CF3)2Te with (CH3)2Cd via the intermediate formation of a CF3Cd compound to form CH3TeCF2CH3. (CF3)2Cd*glyme reacts with (CH3)3Si(OCOCF3) to CF3Cd(OCOCF3)*glyme; during this reaction CF2 is also eliminated.
