Abstract

The reaction of nickel(II) nitrate with 4-(2-bromo-4-methyl-1-phenylazo)-3-amino-5-methy1-2-alkylpyrazoles by refluxing in dimethylformamide in the presence of K2CO3 followed by purification with a column filled with Al2O3 gave [1,10,11,20-tetrahydro-1, 11-dipropyl-3,8,13,18-tetramethyIdibenzo[c,j]dipyrazolo[3,4-f:3′,4′-m] [1,2,5,8,9,12]hexaazacyclotetradecinato(2-)-4,10,14,20]nickel and [1,14,15,20tetrahydro-1, 14-dipropyl-3,7,12,17-tetramethyldibenzo[c,j]dipyrazolo[4,3-g:3′,4′-m] [1,2,5,6,9,12]hexaazacyclotetradecinato(2-)-5,10,15,20]nickel, which were characterized by the results of elementary analysis and the IR, UV, PMR, and mass spectra.
