伯胺和仲胺在氯铂酸存在下与硅反应生成氢和未鉴定的产物，推测为氨基硅烷。1与烯丙基胺、三乙氧基硅烷、氯铂酸形成络合物，沿着有氢。然而，尽管存在氨基氢，烯丙基氨基三甲基硅烷（I）在氯铂酸存在下与三乙氧基硅烷反应，生成少量的四乙氧基硅烷和硅烷，产物假定为3-三乙氧基硅丙基氨基三甲基硅烷。对称四甲基二硅氧烷和I推测得到1，3-双（3-三甲基甲硅烷基氨丙基）四甲基二硅氧烷。这些加合物没有被分离，但乙醇将它们以良好的产率转化为游离胺II和III，并将其分离和鉴定。
Primary and secondary amines with silicon hydrides in the presence ofchloroplatinic acid form hydrogen and unidentified products, presumably aminosilanes. 1 With allylamine triethoxysilane and chloroplatinic acid led to complex products along with hydrogen. However, despite the presence of an amino hydrogen, allylaminotrimethylsilane (I) reacted with triethoxysilane in the presence of chloroplatinic acid to give a small amount of tetraethoxysilane andsilane with a product as-sumed to be 3-triethoxysilylpropylaminotrimethyl-silane. sym-etramethyldisiloxane and I presum-ably gave l, 3-bis (3-trimethylsilylaminopropyl) tet-ramethyldisiloxane. These adducts were not iso-lated, but ethanol converted them in good yield to the free amines II and III, which were isolated and identified.
