Nickel(II) 3-nitro-azacorroles were reacted with 4-amino-4H-1,2,4-triazole to give the 2-NH2-3-NO2-azacorrole and oxadiazole-fused azacorrole, in moderate to good yields. The structures of all the products were characterized thoroughly by NMR, HRMS and X-ray crystallographic analysis.
CHEN et al. (Sun,) studied this question.
