Article abstract of DOI:10.1055/s-1992-26096

A number of 1,3,5-triazino[1,2-a]benzimidazoles 5 and 7 have been prepared by aza-Wittig-type reaction of 2-(triphenylphosphoranylideneamino)benzimidazoles 2 and 6, which were derived from 2-aminobenzimidazoles, with isocyanates under neutral conditions.
