Controlled 1,5-Cyclisation to N-Aminotriazoles and 1,6-Cyclisation to Substituted 1,2,4,5-Tetrazines in Substituted Benzonitrile N-imides from Thermolysis of 2-Hydrazonoyltetrazole Derivatives.
p-Substituted benzonitrile N-imides undergo a 6Π-electrocyclization to give 4-amino-1,2,4-triazoles in the absence of acid.If the nitrile imides are generated in the presence of a proton source such as H2O or organic aci

REACTION OF BENZONITRILE N-(p-NITROPHENYL)IMIDE WITH 5-SUBSTITUTED TETRAZOLES: A NEW ROUTE TO SUBSTITUTED 1,2,4-TRIAZOLES VIA N-HYDRAZONOYLTETRAZOLES
A wide range of phenyl 5-R-substituted (R = aryl, alkyl, amino, halo, H) 1- and 2-hydrazonoyltetrazoles has been synthesized.Substituent effects on the orientation of nitrile imide attack on 5-aryltetrazoles are reported.Thermolysis and fragmentation of t
