长链含氟烷基三氯硅烷及其衍生物的合成和性质已有不少报道,本文报道一类新的含氟磺酰胺基取代的硅烷衍生物的合成.这类化合物可作为无机硅酸盐材料的表面处理剂,由于含氟基团的引入,使被处理的物质具有氟碳表面的一些特性. 3-氧杂全氟烷基磺酰氟(1)和烯丙胺在三氟三氯乙烷(FC-113)中反应,得到对应的N-烯丙基取代的磺酰胺2;2与甲醇钠-碘甲烷反应,得到N-甲基-N-烯丙基取代的磺酰胺3.2和3分别与三氯硅烷在氯铂酸催化下反应,得到含氟磺酰胺基取代的三氯硅烷4
The synthesis and properties of long chain fluorine-containing alkyltrichlorosilanes and their derivatives have been reported. In this paper, we report the synthesis of a new class of fluorine-containing sulfonamide-substituted silane derivatives. These compounds can be used as inorganic silicic acid Salt surface treatment agent, due to the introduction of fluorine-containing groups, so that the treated material has some properties of fluorocarbon surface. 3-oxa perfluoroalkyl sulfonyl fluoride (1) and allyl amine in trifluoro trichloride Ethane (FC-113) to give the corresponding N-allyl substituted sulfonamide 2; 2 reacted with sodium methoxide-iodomethane to give N-methyl-N-allyl substituted sulfonamide 3.2 and 3 were reacted with trichlorosilane in the presence of chloroplatinic acid to give fluorosulfonamido-substituted trichlorosilane 4
