Description

Dissymmetric properties of modified by (+)-tartaric acid intermetallics (IM) of the genetic formula LnNsub(5-x)Cusub(x)Hsub(n) (where Ln=La, Sm, Gd, 0<=X<--4; n3-6) in the reaction of ethylacetoacetonate enantioselective hydration are studied. The effect of the modifying solution pH on the dissymmetpic properties of the catalysts is detected; the maximum optical yield is obserred at pH=5 for IM hydrides containing lanthanum and at pH=9 - for IM hydrides containing samarium and gadolinium
