Lukasik, E. published the artcileSynthesis of 1-arylbenzimidazoles and dibenzo[b,e][1,4]diazepines from 2-(arylamino)aryliminophosphoranes, Synthetic Route of 2622-67-5, the publication is ARKIVOC (Gainesville, FL, United States) (2016), 67-85, database is CAplus.
2-(Arylamino)aryliminophosphoranes, easily obtained from 2-nitrosodiarylamines,were found to be convenient starting materials for simple reactions with common acylating reagents such as acid chlorides and the Vilsmeier reagent. The reactions allowed for the synthesis of 1,2-disubstituted benzimidazoles or dibenzo[b,e][1,4]diazepines, depending on the substituents on the 2-arylamine nitrogen atom.
ARKIVOC (Gainesville, FL, United States) published new progress about 2622-67-5. 2622-67-5 belongs to imidazoles-derivatives, auxiliary class Benzimidazole,Benzene,Benzimidazole, name is 1,2-Diphenyl-1H-benzo[d]imidazole, and the molecular formula is C19H14N2, Synthetic Route of 2622-67-5.
