Ditopic Macropolycyclic Complexes: Synthesis of Hybrid Phthalocyaninoclathrochelates
摘要:
A remetalation (a capping group exchange) reaction of the boron-antimony-capped iron(II) clathrochelates with zirconium and hafnium(IV) phthalocyanines in CH2Cl2/CH3OH medium afforded the hybrid phthalocyaninoclathrochelates in a practically quantitative yield. The complexes obtained have been characterized both on the basis of elemental analysis, PD mass spectrometry, IR, UV-vis, Fe-57 Mossbauer, and NMR spectroscopies, and crystallographically. An encapsulated iron(II) ion in an intermediate between a trigonal-prismatic and a trigonal-antiprismatic environment of six nitrogen atoms of the macrobicyclic ligand was found to be in a low-spin state. The cyclic voltammograms show irreversible oxidation and reduction waves assignable to Fe3+/Fe2+ couples of macrobicyclic fragments and to phthalocyanine macrocycles.

Abstract— Two synthetic approaches for obtaining of zirconium and hafnium dihydroxophthalocyaninates (i.e. (a) that using the zirconium and hafnium alkoxides as the reactive precursors and (b) hydrolysis of zirconium and hafnium dichloridophthalocyaninates) were evaluated. Reactivity of zirconium and hafnium dihydroxophthalocyaninates in their exchange reactions with β-diketones and with decanoic acid was

Synthesis and spectral properties of Zr(IV) and Hf(IV) phthalocyanines with β-diketonates as axial ligands
Abstract The series of new zirconium(IV) and hafnium(IV) phthalocyanines with various β-dicarbonyl ligands were prepared via direct interaction between di(chloro)zirconium(IV) or hafnium(IV) phthalocyanines and free β-diketones and also with 4-benzoyl-3-methyl-1-phenyl-2-pyrazolin-5-one. The structure of the obtained bis(β-dicarbonilato) zirconium(IV) and hafnium(IV) phthalocyanines was studied by
