HETEROCYCLIC COMPOUNDS CONTAINING DIAZO AND CYANO GROUPS. 1. DIAZOACETONITRILE DERIVATIVES IN THE SYNTHESIS OF 5-HALO-1H-1,2,3-TRIAZOLES

Article abstract of DOI:10.1007/BF00506405

Carbonyl-substituted derivatives of diazoacetonitrile have been obtained by the diazotation of amines and by diazo-group transfer which, under the action of hydrogen halide, have been converted into 4-carbonyl-substitued 5-halo-1H-1,2,3-triazoles.The stru
