Synthesis and Characterization of a Tetraaza Macrocyclic Nickel(II) Complex Bearing Two Amidine Pendant Arms: Unprecedented Strong Metal-Pendant Arm Interaction

摘要

There has been continuing interest in the preparation of new polyaza macrocyclic compounds bearing various types of functional pendant arms,since chemical properties of such compounds are influenced by the nature of the functional groups. Some coordinated organic nitriles (R-CN) in transition metal complexes react with H_2O,R'OH,or R"-NH_2 under relatively mild conditions to produce amides (RCONH_2),imidate esters (R-C(=NH)-OR'),or amidines (R-C(=NH)-NHR").
