The synthesis and characterization of new copper(II) phthalocyanines containing four 20-member tetraazadioxa macrocyclic moieties

The synthesis and characterization of a copper(II) phthalocyanate substituted with four 20-membered tetraaza-dioxa macrocycles from 21,22-dibromo-2,8,11,17-tetra(toluene-p-sulphonyl)-1,2,3,4,5,6, 7,8,9,10,11,12,13,14,15,16,17,18-octadecahydrobenzox[l] [2,8,11,17]tetraaza[4,13]dioxacyclodi-contine is described. The detosylation of the macrocyclic aza groups provides four tetraaza-dioxa mixed donor sites for binding metal ions, The structures of the compounds were determined by elemental analysis, H-1, C-13 NMR, IR and MS spectral data.
