Abstract A study is presented on the scope of the method to obtain 1H-4,5-dihydroimidazolium salts 3 by dehydrogenation of 1,3-di and 1,2,3-trisubstituted imidazolidines 2. Of the dehydrogenating agents used, N-bromoacetamide leads to the best results, providing a simple and general method to prepare salts 3.
