Procedure

For instance, 2-trichlorosilyl-1,3-butadiene [II-d]and 2-triloweralkoxy silyl-1,3-butadiene [II-a]can be synthesized by reacting 1,4-dichloro-2-butyne [IV]and trichlorosilane [V]in the presence of a platinum type catalyst to obtain 1,4-dichloro-2-(trichloro)silyl-2-butene [VI]is then reacted with Zn in a tetrahydrofuran solvent to prepare 2-(trichloro)silyl-1,3-butadiene[II-d], and further reacting the 2-(trichloro)silyl-1,3-butadiene II-d with a lower alcohol in the presence of a base, such as triethylamine, as shown by the following Formula (C): ##STR14##
