Cis Isomer

Optically active trans-2-phenyl-3-p-tolyloxirane and cis-2-phenyl-3-p-tolyloxirane were synthesized and the kinetics of their racemization and geometrical isomerization were studied.The slower rate of racemization of the cis-isomer compared with that of the trans is attributed to the conrotatory opening of the oxirane ring.

Parent Ligand

The kinetics of the hydrogenation of (Z)-(a)-N-acetamidocinnamic acid catalysed by Rh complexes of the optically active layer-phosphines 2-7 was examined. The turnover was calculated from the consumption of hydrogen during the reaction. The catalytic activities of the layer-phosphines 2-7, which depend on the position of the borneoxy substituents on the phenyl rings, were compared with the catalytic activity of the parent ligand dppe 1
