Abstract

Abstract–A study about the scope of the method for the attainment of 4, 5-dihydro-1H- imidazolium salts by dehydrogenation of N, N-dibenzyl-and N-aryl-N-benzylimidazolidines is presented. Employed dehydrogenating agents were N-bromoacetamide (NBA), N- bromosuccinimide (NBS), carbon tetrachloride and 1, 3-dibromo-5, 5-dimethylhydantoin (DBDMH). DBDMH was the choice reagent due to the purity of the attained products, ...
