The highly reactive silyltriflates are valuable silylating reagents. Aminosubstituted silyltriflates R(Et2N)3-nSiOTfn (n = 1, 2) are obtained by treatment of di-, tri- and tetraaminosilanes with trifluoromethanesulfonic acid. The title compounds show a versatile reactivity towards nucleophiles. Reactions with a stoichiometric ratio of 1:1 proceed exclusively under substitution of the triflate group
高反应性的甲硅烷基三氟甲磺酸盐是有价值的甲硅烷基化试剂。通过用三氟甲磺酸处理二,三和四氨基硅烷,获得氨基取代的甲硅烷基三氟甲磺酸盐R(Et 2 N)3- n SiOTf n(n = 1,2)。标题化合物显示出对亲核试剂的通用反应性。化学计量比为1:1的反应仅在三氟甲磺酸酯基团的取代下进行。氨基显示出惰性行为。因此,标题化合物是氨基甲硅烷基的理想递质。它们已通过NMR光谱(29 Si,1 H)进行了表征。
