Abstract
1,2-Dialkyl-2,3-dihydrobenzimidazoles have been produced by reduction of the aromatic parent compounds with lithium aluminium hydride and also directly by cyclization of the appropriate nitrenes generated from azides or from nitro-compounds by deoxygenation with trialkyl phosphites. The factors influencing the stability of the title compounds have been studied.Keywords
