Abstract
PURPOSE: To prepare the title compound useful as an additive for polymers or an intermediate of drugs, pesticides, etc., in high yield, while recovering and reusing the reaction by-products, by reacting an organo-tin isocyanate with an organo- silicon compound.
CONSTITUTION: The title organo-silicon isocyanate of formula III prepared by reacting (A) a compound of formula I (R1 is 1W8C alkyl; m is 1W3) with (B) a compound of formula II (R2 is alkyl, alkenyl or aryl; n1 is 0W3; X is halogen), in an inert solvent or in the absence of solvent, pref. at 60W120°C. The produced objective product is easily separated from organo-tin halide produced as a by-product, only by the distillation, and the by-product can be easily recovered and reused as the raw material by reacting with urea.
