  Influence of Substituents, Reaction Conditions and Central Metals on the Isomer Distributions of 1(4)-Tetrasubstituted Phthalocyanines

  摘要：

  The 1(4)- and 2(3)-tetraalkoxy-substituted nickel (5), copper (6), and metal-free phthalocyanines 7 and 8 were synthesized from the corresponding substituted phthalonitriles 2 and 4, respectively, and the four structural isomers formed for each phthalocyanine were separated by HPLC. In the case of 1(4)-tetraalkoxy-substituted phthalocyanines the ratio of the four isomers was found to be different from the expected statistical distribution of D-2h:C-5:C-2v:C-4h = 12.5:50:25:12.5. For the 1(4)-substituted metal-fret: phthalocyanine 7 a very high proportion of the C-4h isomer (87%) is formed. In the case of the 1(4)-substituted metal phthalocyanines 5 and 6 the strikingly low proportion of the D-2h isomer (found: 2-4% compared to statistical distribution: 12.5%) is interpreted by a template mechanism (given in Scheme 2) in which strong steric hindrance of the respective neighboring groups prevent the formation of the D-2h isomer. To investigate further the mechanism of formation of phthalocyanines the synthesis of 1(4)- and 2(3)-tetraalkoxy-substituted metal phthalocyanines containing chiral alkoxy groups (13-17) was studied under different reaction conditions starting from the corresponding alkoxy-substituted phthalonitriles 10 and 11. In all investigated cases the chiral alkoxy groups in the starting phthalonitrile again affect the distribution of the structural isomers of the formed phthalocyanines, lending to a higher proportion of the C-4h isomer in comparison with the 1(4)-tetraalkoxy-substituted phthalocyanines with racemic alkoxy groups.

  The invention relates to a process for preparing alkoxy-substituted, metal-containing phthalocyanines of the formula (I) where R is substituted or unsubstituted alkyl or cycloalkyl, M is a divalent metal atom, metaloxy or a trivalent or tetravalent substituted metal atom, characterized in that the phthalonitrile of the formula (II) is reacted in the presence of a metal salt and a base in a water-miscible solvent.
