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.
Ligand effects on Negishi couplings of alkenyl halides

supporting information; experimental part, p. 3818 - 3821 (2011/10/01)
Negishi couplings at olefinic centers do not always occur with the anticipated maintenance of stereochemistry. The source of erosion has been traced to the ligand, and a modified method has been developed that solves the stereochemical issue and significantly improves yields of Negishi couplings in general.
