Conclusions
-
1.
The direction of the reaction of bisalkylidene- and bisbenzylidenethylenediamines with acid chlorides depends on the polarity of the solvent used.
-
2.
Acylation of bisalkylidenethylenediamines and bisbenzylidenethylenediamines in highly polar media leads to the formation of 2-alkyl- and 2-aryl-substituted N,N′-diacylimidazolidines.
