The regioselective hydrogenation of unsaturated compounds was carried out by catalysis with platinum-zeolite coupled with an organosilicon alkoxide using a chemical vapor deposition method (CVD-modified catalyst).In hydrogenation of a mixture of 1-nonene and trans-4-nonene by this catalyst, the reaction rate of 1-nonene was much greater than that of trans-4-nonene.In particular, when diphenyldiethoxysilane was used as the coupling reagent on the platinum-zeolite, excellent selectivity was produced.Further, it was elucidated that the terminal carbon-carbon double bonds are preferentially hydrogenated in the case of some compounds possessing more than one carbon-carbon double bond.
