Abstract
In the addition of lauryl mercaptan (LSH) to dimethyl maleate (DMM) and dimethyl fumarate (DMF), the ratio of the second-order rate constants for these geometrical isomers, k′DMF/k′DMM, was larger in the cases with polymeric amine and diamine as catalyst than in the cases with low-molecular-weight monoamines. In the addition reaction catalyzed by optically active amines, only the polymeric amine gave optically active product and the absolute configuration of the product obtained from DMF was opposite to that obtained from DMM.
