Treatment of o-azidobenzaldimines 2 with tertiary phosphines in methylene chloride at 0 deg C leads to the corresponding 2,3-diamino-2H-indazole derivatives 3 by cyclization of the intermediate phosphazide.Compounds 3 react with isocyanates, carbondioxide
Intramolecular Trapping of a Phosphazide by an Imine: Formation of 2,3-Diamino-2H-indazole Derivatives from o-Azidobenzaldimines and Tertiary Phosphines
