Synthesis of {15-benzyloxy-3,7,11,17-tetraazabicyclo[11.3.1]heptadeca-1(17),13,15-triene}nickel(II) perchlorate and its analogs, and their catalytic behavior in reductive debromination of 1-bromo-4-tert-butylbenzene
Abstract New nickel(II) complexes with macrocyclic ligands bearing benzyloxy [( 5 ), ( 9 )], 2-methylbenzyloxy ( 7 ), 3-methylbenzyloxy ( 8 ), and hydroxy ( 6 ) groups on the pyridine ring have been synthesized. Structures of the hydroxy substituted macrocyclic ligand (L-OH·3HCl·H 2 O), and the benzyloxy substituted ligand (L-OBn·3HCl ) and its nickel(II) complex ( 5 ), as well as an analogous Ni(II) complex
