A Synthesis of Novel Non-symmetrical Phthalocyanines

Synthesis, Separation and Characterization of Unsymmetrically Substituted Phthalocyanines

“…In all statistical condensations of tetraphenylphthalonitrile (1) with 2a-d, we have observed in accordance with that 1 does not form (1,2,3,4,8,9,10,11,15,16,17,18,22,23,24,25-hexadecaphenylphthalocyaninato)nickel(I1) by selfcondensation due to steric hindrance of the phenyl groups. In contrast to ref.…”

“…(1,4- 9,10,11,15,16,17,18,22,23,24,nickel(ZI) (7c): Yield 1.5 mg (0.2%). -'H NMR: F = 0.8-2.0 (br, 22H, CH2 and CH3), 3.94 (t, 4H, CH2),…”

New Approach to the Synthesis of Planar Binuclear Phthalocyanines of Mg, Zn and Rare Earth Elements

“…For the spectra of the REE complexes 3e-g registered using 2,5-dihydrobenzoic acid (DHB) as a matrix signals [M + -2OAc+2DHB] were detected instead of molecular ions ([M + ]). This result additionally confirms earlier established fact [11] of Ln-OAc bond ionic nature. In the absence of matrix the corresponding spectra could not been obtained, which is likely to be related with low stability of molecular cation-radicals ([M + ]).…”

Synthesis, Separation and Characterization of Naphthobenzo-condensed Porphyrazinato Nickel(II) Complexes

“…In all statistical condensations of tetraphenylphthalodinitrile (12) with 3,7,11 respectively, in accordance with reference [18] no hexadecaphenylphthalocyaninato nickel(II) is formed. In agreement with the reported data [1,19], but in contrast to reference [18], we obtained naphthobenzo-condensed porphyrazines of the types AAAB and AABB in which two tetraphenyl units are in the neighbouring positions.…”
