A series of symmetrically substituted phthalocyanines have been synthesized from 3,6-dialkoxyphthalonitrile and the corresponding metal salts. All of these complexes are extremely soluble in chloroform. Their melting points vary greatly with their different substituents. Their structures are confirmed by elemental analysis, 1H NMR, UV-VIS.

This paper describes the electronic structure of (α,α′-n-OC5H11)8-H2Pc and (α,α′-n-OC5H11)8-Ni(ii)Pc and highly efficient carbonyl reductions catalyzed by Ni(ii)Pc.
To obtain more structural information of (phthalocyaninato)ruthenium compounds, an EXAFS investigation was carried out on amorphous tBu4PcRu (1), tBu4PcRu(3-Clpy)2 (2), PcRu(3-Fpy)2 (3) and (C5H11O)8PcRu(3-Clpy)2 (4). Structural models for the four compounds are deduced from the atomic distances determined around the metal centre. A dimeric structure was found for 1, while bisaxial arrangement of the

The reactions of 3,6-dipentoxyphthalonitrile (A) in the 1-pentanol - magnesium pentylate medium with phthalonitrile, 2,3-di(methylsulfanyl)-2-butenedinitrile, and 2,3-dihydro-1,4-dithiin-5,6-dicarbonitrile (B) were performed. Unsymmetrically substituted porphyrazines A3B were prepared and studied. The influence of the structure of fragment B on the spectral characteristics of the porphyrazines was examined.

With results on (S(4))PzH(2) and (SA(3))PzH(2) in hand, including crystallographic work on the latter, a general chemical physical investigation has been carried out of all the symmetrical and unsymmetrical free-base macrocycles. The structures of the species (S(2)A(2))PzH(2) and (A(4))PzH(2). were elucidated by single-crystal X-ray crystallography
