The perflouroalkynyl derivatives of germanium and tin (CH3)nM(C CRf)4-n (MGe, Sn; Rf CF3, CF2CF3, CF(CF3)2; n3, 2; but not all combinations) react with trimethyl-trifluoromethyltin at 150° to give the cyclopropenyl derivatives (CH3)nM(F2)4-n. The reaction probably involves the addition fo difluorocarbene to the carbon-carbon triple bond, and the carbene is probably produced in the singlet state
