Özet

Novel phthalocyanines with biphenyl substituents and ester groups that are readily soluble in organic solvents were synthesized from a phthalonitrile derivative obtained by displacement of the -CH proton in 1-chloro-3,4-dicyano-6-(1,1-dicarbethoxymethyl)benzene with 4-(chloromethyl)biphenyl, followed by cyclotetramerization in the presence of metal salts {CuCl2, Pb(CH3COO)(2)center dot 3H(2)O, CoCl2 and Zn(CH3COO)(2)}. Transesterification of malonyl esters occurred during the cyclotetramerization of dinitrile with CuCl2, Pb(CH3COO)(2)center dot 3H(2)O in 1-pentanol in the presence of DBU. The structures of the newly synthesized molecules were verified using elemental analysis, H-1 NMR, FT-IR, MicroTOF mass and UV-vis spectral data. (C) 2008 Elsevier Ltd. All rights reserved.
