Del Vecchio E, Boga C, Forlani L, Tozzi S, Micheletti G, Cino S.
PMID: 25615685
J Org Chem. 2015 Feb 20;80(4):2216-22. doi: 10.1021/jo5027244. Epub 2015 Feb 03.

The reaction between 1,3,5-tris(N,N-dialkylamino)benzene derivatives and 2 equiv of p-substituted benzenediazonium salts gives dicationic species which collapse to new benzimidazole derivatives with expulsion of p-substituted anilines. The presence of electron-withdrawing groups on the benzenediazo moiety of the dicationic species...
