摘要: Silyl carbamates are produced by the reaction under suitable reaction conditions of silanes bearing at least one silicon-hydrogen bond of the formula: R.sub.4-x SiH.sub.x with an ammonium carbamate of the formula: R'R"NH.sub.2.sup..sym. R'R"NCO.sub.2.sup..crclbar.. This novel route is much simpler and more direct than those previously known and provides a new classes of silyl carbamates.
