Trifluoromethanesulfonates of silicon, germanium, tin and lead are obtained by cleavage of the corresponding phenyl derivatives with CF3SO3H. Selective cleavage of the tincarbon bond is observed in the case of silyl- and germylstannanes. Reaction of bis(trifluoromethanesulfonates) with lithiumorganic compounds leads to functional substituted triflate derivatives.
硅,锗,锡和铅的三氟甲磺酸盐是通过用CF 3 SO 3 H裂解相应的苯基衍生物而获得的。在甲硅烷基和二十烷基锡烷基锡的情况下,锡碳键的选择性裂解被观察到。双(三氟甲磺酸盐)与锂有机化合物的反应导致官能取代的三氟甲磺酸酯衍生物。

elements of group 14. Syntheses are characterized by high regioselectivity and short reaction times at low temperatures. Exchange processes similar to metal halogenexchange are not observed. In this way the selective preparation of higher oligomers of silicon, germanium and tin has been made possible.
