Synthesis And Characterization Of A Novel 32-Membered Unsymmetrical Dinucleating [N12] Macrocycle: Preparation Of Bimetallic Complexes M2lx2(Clo4)2 (M = Zn, Cd Or Hg; X = Cl, Ncs Or No3), Z. A. Siddiqi Dr, Mohammad Mansoob Khan Dr

The condensation reaction of N-acetylaniline with 1,3-diaminopropane in 2 : 1 mole ratio under reflux condition generates an intermediate species having C55N bonds. The in situ reaction of the intermediate with HCHO and 1,3-diaminopropane in the presence of perchloric acid results in an off-white solid product. Analytical, FAB mass, IR, 1H NMR and electronic spectral data of this solid are consistent with the formation of the dihydroperchlorate salt of an unsymmetrical 32-membered [N12] macrocycle [L.2HClO4] via a capping mechanism of the intermediate species. Reactions of [L 2HClO4] with Group 12 metal salts, MX2, and their precursors, [M(Ph3P)2Cl2], produce bimetallic complexes …
