Treatment of 3- or 4-nitrophthalonitrile with 1,2:5,6-di-O-isopropylidene-alpha-d-glucofuranose or 1,2:3,4-di-O-isopropylidene-alpha-d-galactopyranose in the presence of K(2)CO(3) gave the corresponding glycosubstituted phthalonitriles. These precursors underwent self-cyclisation, or mixed-cyclisation with the unsubstituted phthalonitrile, to afford the tetra- or mono-glycosylated zinc(ii) phth...

The present work relates to the synthesis and spectral properties of erbium sandwich type metal complexes containing tetraanthraquinoporphyrazine as well phthalocyanine fragments. By reacting tetraanthrachinoporphirazine (lutetium) acetate with excess phthalonitrile, 4-chloro, 4-bromophthalonitrile unsubstituted sandwich-type an unsymmetrical structure were obtained. compounds extracted from re...

Novel mononuclear Zn(ii) 4, Co(ii) 5 and Cu(ii) 6 metallophthalocyanines have been synthesized from 4,4'(ethane-1,1-p-phenol-2,2-p-phenoxy)phthalonitrile 3, which can be obtained by the reaction of 4-nitrophthalonitrile 1 with 1,1,2,2-tetrakis(p-hydroxy-phenyl)-ethane 2. The target water-soluble derivatives of 7-9 were acquired from a boiling suspension of the compounds in aqueous 20% KOH solut...
