1,3-Dipolar Cycloaddition of Carbodiimides and Nitrilimines: Synthesis and Mechanistic Study of 5-Amino-1,2,4-triazoles

An effective 1,3-dipolar cycloaddition was developed for the synthesis of 5-amino-1,2,4-triazoles by reacting hydrazonoyl hydrochlorides (nitrilimines) with carbodiimides in the presence of triethylamine as a base. Both symmetric and asymmetric carbodiimi

Reaction of C-(Triphenylphosphinimido)hydrazones with Isocyanates as a Route to 5-Arylamino- and 5-Alkylamino-1H-1,2,4-triazoles

Treatment of C-(triphenylphosphinimido)hydrazone (1) with aryl and alkyl isocyanates results in 5-arylamino- and 5-alkylamino-1H-1,2,4-triazoles (5), often accompanied by a minor quantity of the triazol-5-one (7).The related ortho-acyl-substituted substrates (8) react with phenyl isocyanate to give triazoloquinazolines (12) or (13) through the intermediacy of aminotriazoles (11).
