    摘要: 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.

    摘要: 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.

    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.
