Rhodium-Catalyzed Amination of Aromatic Olefinsamines. Styrene as the hydrogen acceptor gave concomitantly ethylbenzene. In the presence of 1,5-cyclooctadiene (.) preferential reduction to cyclooctene takes place. The addition of . reduces the rate of the reaction, but also the amount of ethylbenzene produced. Here, for the first time the ratio

Enantioselective Catalyses CXXXV . Stereoselective Hydrogenation of Folic Acid and 2-Methylquinoxat C6 of the pteridine system. With rhodium(I) catalysts of optically active phosphanes, which were immobilized on silical gel, the hydrogenation in aqueous solution can be controlled stereoselectively. The highest diastereomeric excess of .. 40% is obtained with (−)-.-containing catalysts. The hydr
