On the nitro group transfer from 2-nitro-4,5,6,7-tetrachloro-2H-benzotriazole and 2-nitro-2H-phenanthro[9,10-d]triazole to secondary amines

The synthesis of 2-nitro-4,5,6,7-tetrachloro-2H-benzotriazole 1 and of 2-nitro-2H-phenanthro[9,10-d]-triazole 2 and their transfer of the nitro group to give 1-nitropyrrolidine 4a and 1-nitromorpholine 4b in high yields when reacted with pyrrolidine or morpholine are reported. The reaction of 1 also gives the pyrrolidinium and morpholinium salts 5a-b of 1 .
