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。

Exposure of solutions of Tb(N(SiMe3)2)3 with SiCl(NEt2)3 in tetrahydrofuran to dry ammonia results in polymeric xerogels. Heating these gels in ammonia leads to amorphous Tb:SiNx phosphors that exhibit bright green luminescence under UV irradiation. MAS‐NMR and combustion analysis reveal that the phosphors are silicon nitride materials analogous to those typically produced by sol–gel routes. Photoluminescence behavior is similar to that of Tb:SiNx or Tb:SiO2 films produced by ion implantation that show good electroluminescence activity.
