A bissilylnorbornane compound is prepared by reacting 2,5-norbornadiene with a hydrogenchlorosilane in the presence of a mixture of a palladium compound and a phosphite or a palladium complex having a phosphate ligand as a catalyst. The bissilylnorbornane compound can be produced in high yields while suppressing formation of by-product nortricyclene.

A halopropyldimethylchlorosilane is prepared by reacting dimethylchlorosilane with an allyl halide in the presence of an iridium catalyst. The reaction is effected in the presence of an internal olefin compound, typically 1,5-cyclooctadiene. The internal olefin compound suppresses deactivation of the iridium catalyst during reaction. Using a smaller amount of the iridium catalyst, the process produces the halopropyldimethylchlorosilane in high yields.

By reacting 4-vinyl-1-cyclohexene with a hydrogenchlorosilane compound in the presence of a platinum catalyst to give a reaction solution containing a monosilyl compound, removing the residual 4-vinyl-1-cyclohexene and isomers thereof from the reaction solution, and reacting the monosilyl compound again with the hydrogenchlorosilane compound, an organic silicon compound in which the two double bonds in 4-vinyl-1-cyclohexene have been hydrosilylated is produced in high yields.
摘要:
A (meth)acryloxy-bearing alkoxysilane is isolated and purified to a high purity by distilling a reaction solution containing the (meth)acryloxy-bearing alkoxysilane in a thin-layer distillation device at a temperature of 90-160° C. and a vacuum of 1-15 mmHg. The resulting alkoxysilane product does not give rise to the quality problem that the product will gradually whiten during storage owing to contact with air. The occurrence of self-polymerization of the alkoxysilane is restrained.

摘要:
Disclosed are a conductive pyrrole derivative monomolecular film covalently bonded to a substrate surface and method of manufacturing the same, and a monomer used for forming the conductive pyrrole derivative monomolecular film and method of manufacturing the same. The invention relates to a monomolecular ultrathin film comprising 1-pyrrolyl groups and silicon groups. The monomer used for forming the film is provided by reacting .omega.-(1-pyrrolyl)-1-alkene compound to a monosilane derivative compound, in which three out of four hydrogen atoms of monosilane are replaced with halogen or alkoxy groups, in the presence of a transition metal catalyst. A substrate is dipped and held in a nonaqueous solution of the above-noted monomer, thus chemically bonding a monomolecular film to a substrate surface. Furthermore, a polypyrrole derivative ultrathin film is formed by the electrolytic or catalytic polymerization of the monomolecular film.
