Optically active (+)-bornyl- and (-)-menthylammonium platinates were synthesized starting from H2[PtCl6] ? 4H2O and hydrochlorides of the corresponding amines. Catalytic activity of the complexes in the hydrosilylation reactions of 1,3-divinyl-1,1,3,3- tetramethyldisiloxane with 1,1,3,3-tetramethyldisiloxane and acetophenone with diphenylsilane was studied. The addition of the siloxanes leads to a predominant formation of β-adduct. Activity of the catalysts, evaluated on the 50% conversion of the substrate, decreases in the following sequence: (-)-(menthylNH3)2[PtCl6] > (Et 3NH)2[PtCl6] > (+)-(bornylNH 3)2[PtCl4] > (+)-(bornylNH3) 2[PtCl6]. Asymmetric induction is observed in the hydrosilylation of aceto-phenone in the presence of (+)-(bornylNH 3)2[PtCl n ] (n = 4, 6); (+)-(bornylNH 3)2[PtCl6] showed the highest catalytic activity and selectivity. The hydrosilylation of acetophenone gave 1-phenylethoxy(diphenyl)silane, 1-phenylvinyloxy(diphenyl)silane, and 2-phenylethyl-2-diphenylsiloxy(diphenyl)silane as the products.

The cathode directs the way to the epimeric menthylamines. The reduction of menthone oxime on a Hg cathode generates (-)-menthylamine as the major product, whereas a Pb cathode gives access to (+)-neomenthylamine (see scheme). Insitu decoration of the Pb cathode by small amounts of additives results in clean and quantitative conversions. Furthermore, Pb corrosion is completely prevented in this practical method. Copyright
