ABSTRACT:
By subjecting to hydrosilylation a hydrogendimethylalkoxysilane compound and an N-silylated allylamine compound in the presence of a platinum catalyst, adding an alcohol to the reaction product to effect desilylation reaction, and hydrolyzing the resulting 3-aminopropyldimethylalkoxysilane compound, 1,3-bis(3-aminopropyl)tetramethyldisiloxane is prepared. The end product free of isomers and of quality can be prepared through simple steps, at a low cost and in high yields.
