Abstract
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.
