ChemInform Abstract: Noncatalyzed Conjugate Addition Reaction of Alkylaluminum Compounds to 5-Methylene-2,4-imidazolidinedione Derivative

A noncatalyzed conjugate addition reaction of alkylaluminium compounds to 1,3-dibenzyl-5-methylene-2,4-imidazolidinedione 1 led to the exclusive formation of single and double conjugate adducts (2 and 3, respectively). The ratio of 2 : 3 depended on the reaction temperature and the concentration of 1.
