1,3‐Dibromo‐5,5‐dimethylhydantoin as a New Imidazolidine Dehydrogenating Agent: Synthesis of 4,5‐Dihydro‐1H‐imidazolium Salts.

Abstract

Imidazole derivatives R 01901,3-Dibromo-5,5-dimethylhydantoin as a New Imidazolidine Dehydrogenating Agent: Synthesis of 4,5-Dihydro-1H-imidazolium Salts. -The conversion of imidazolines to the corresponding 4,5-dihydro-1H-imidazolium salts is investigated. DBMH is found to be the optimal reagent. -(CATERINA, M. C.; FIGUEROA, M. A.; PERILLO, I. A.; SALERNO*, A.; Heterocycles 68 (2006) 4, 701-712; Dep. Quim. Org., Fac. Farm. Bioquim., Univ.
