The amine moiety of aminals adds to dimethyl maleate via azomethine ylid intermediates. The products of this reaction, in turn, cause dimethyl maleate to isomerize to dimethyl fumarate.

โฆ Synopsis
EARLY experimental work on the kinetics of thermal cis -trans isomeriza--tions in the gas phase indicated that these reactions were typical uni-1 molecular processes . For three of these reactions, however, the tempera- ture dependence of the rate coefficients was reported to be anomalously small. Thus for the isomerizations of cis-2-butene2, dimethyl maleate and dimethyl citraconate4 respectively, frequency factors of 10ยฐ'3, 105'1
