silanes. GeX bonds (X = Br, Cl, OR, H) are unreactive. Allylsilicon and allylgermanium bonds are broken under mild conditions and in high yields, leading to the corresponding fluorosilane or fluorogermane. With bifunctional silanes, it is always possible to obtain the difluorinated derivatives.
描述了嵌入在石墨中的SbF 5作为有机硅和-锗衍生物的氟化剂的用途。SiO和SiCl键很容易断裂,而SiH和SiS键仅在双官能硅烷中具有反应性。GeX键(X = Br,Cl,OR,H)没有反应性。烯丙基硅键和烯丙基锗键在温和条件下以高收率断裂,从而生成相应的氟代硅烷或氟代锗烷。使用双官能硅烷,总是有可能获得二氟化衍生物。
