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
锗和锡的perflouroalkynyl衍生物(CH 3)ñ M(CCR ˚F)4- Ñ(MGe,锡; R ˚F CF 3,CF 2 CF 3,CF(CF 3)2 ; Ñ 3 ,2;但不是所有组合)与三甲基三氟甲基锡在150°下反应,得到环丙烯基衍生物(CH 3)n M(F 2)4- n。该反应可能涉及将二氟卡宾添加到碳-碳三键中,并且卡宾可能是通过锡化合物的热解以单线态生成的,因为它是立体定向地将顺式和反式-丁烷-2的双键添加的。。卡宾还增加了三甲基乙烯基硅烷的双键,但没有增加环丙烯基衍生物的双键。讨论了新化合物的光谱性质。
