摘要：

An axially substituted chloro complex of tetra-t-butylphthalocyaninato-chromium was prepared by chromium insertion into metal-free tetra-t-butylphthalocyanine (TTBuPcH2). By extracting the soluble components into acetonitrile and pentane a product with the composition TTBuPcCrCl2H was obtained. It was shown to contain anionic phthalocyanine moieties. In aqueous sodium hydroxide mu-oxo-bis(tetra-t-butylphthalocyaninato)chromium(III) is formed. Boiling pyridine replaces one of the Cl ligands yielding TTBuPcCrCl.2py. Thermogravimetric analysis showed the elimination of both pyridine molecules between 105 and 215-degrees-C and Cl elimination at higher temperatures. TTBuPcCrCl.2py is oxidized by thionyl chloride to TTBuPc(-I)Cr(III)Cl2. Reaction with pyridine reforms TTBuPcCl.2py. All newly synthesized products were characterized by elementary analysis, IR, UV-Vis and FAB mass spectrometry.
