1,8,9,20-Tetrahydro-3,6,9-trimethyl-1,8-diphenyldibenzo[c,m]-dipyrazolo[3,4-f:4′,3′-j][1,2,5,8,9,12]hexaazacyclotetradecene in reactions with Ni(II), Pd(II), and Cu(II) salts

The reactions of N-monomethylated 1,8,9,20-tetrahydro-3,6-dimethyl-1,8-diphenyldibenzo[c,m]dipyrazolo[3,4-f:4′,3′-j]-[1, 2, 5, 8, 9, 12]hexaazacyclotetradecene with Ni(II), Pd(II), and Cu(II) salts were studied. It is shown that the introduction of an N-substituent leads to a significant change in the chemical properties of the macroheterocyclic ligand.
