Abstract

Abstract The effect of the chlorine position on the C-Cl bond hydrogenolysis and the enantioselective hydrogenation of Cl substituted (E)-2, 3-diphenylpropenoic acid derivatives has been studied over cinchonidine-modified Pd/Al 2 O 3. In contrast to the fast hydrodechlorination of the β-phenyl-para-Cl substituted acids the Cl on the α-phenyl ring was barely hydrogenolized. These observations were interpreted by the different ...
