Abstract
1,10,11,20-Tetrahydropyrazolo[3,4-f:3′,4′-m]dipyrido[2,3-c:2′,3′-j][1,2,5,8,9,-12] hexaazacyclotetradecene derivatives were obtained by the reaction of nickel nitrate, palladium chloride, potassium tetrachloroplatinate, or copper sulfate with 5-amino-3-methyl-4-(2-chloro-3-pyridylazo)-1-R-pyrazoles in dimethylformamide in the presence of potassium carbonate and were characterized by the results of elementary analysis and data from the IR, UV, PMR, and mass spectra.
