Abstract
Some macrocyclic compounds containing pyridinc have been synthetized: 3,6,9,15-tetraazabicyclo[9.3.1]pentadeca1(15),11,13-triene(1), 3,7,10,16-tetraazabicyclo[10.3.1]hexadeca-1(16),12,14-triene(2), 3,7,11,17-tetraazabicyclo[11.3.1]heptadeca-1(17),13,15-triene (3), and 7-methyl-3,7,11,17-tetraazabicyclo[11.3.1]heptadeca-1(17),13,15 trienc (4). The protonation reactions of these ligands were studied by potentiometric and 1 H NMR techniques
