Conclusions
-
1.
The methyl and ethyl esters of maleic acid form 1∶1 and 2∶1 adducts with the methyl and ethyl esters of malonic and succinic acids in a reaction initiated by tert-butyl peroxide with high conversion (from 85 to 100%) and yield (from 75 to 100%).
-
2.
Ethyl malonate and the alkyl succinates form two types of adducts with the alkyl maleates as a result of addition at the α-carbon atoms of the acid and alcohol segments of the ester. The addition of methyl malonate to alkyl maleates occurs only at the methylene group.
-
3.
The alkyl malonates and methyl succinate predominantly add two molecules of alkyl maleate.
