The Redox-Active Chromium Phthalocyanine System: Isolation of Five Oxidation States from Pc Cr to Pc Cr.

The preparation and structural characterization of a series of chromium phthalocyanine complexes with multiple metal and ring oxidation states were achieved using PcCr (1) (Pc=phthalocyanine) or PcCr (THF) (1⋅THF ) as starting materials. The reaction of soluble 1⋅THF with Br or I gave the PcCr halide complexes PcCrX(THF) (X=I/I , Br; 3, 4, respectively). Treatment of 1 with 0.

Phthalocyanines as an alternative to soluble polymer-supported platforms in organic synthesis.

Some small molecules, such as phthalocyanines, capable of exhibiting greatly enhanced capacities and acting as internal tags, are shown to be effective as replacements for polydisperse polyethylene glycols, in soluble polymer-supported type synthesis of some piperidine and piperazine derivatives.

Synthesis of 2,3,9,10,16,17,23,24-Octaalkynylphthalocyanines and the Effects of Concentration and Temperature on Their (1)H NMR Spectra.

The syntheses of 3,4- and 4,5-diiodophthalonitriles are described. Coupling of the latter compound with Pd(PPh(3))(2)Cl(2) and 1-octyne, 1-heptyne, 1-hexyne, 1-pentyne, and 3,3-dimethyl-1-butyne gave a series of 4,5-dialkynylphthalonitriles. Hydrogenation of 4,5-bis(1-pentynyl)phthalonitrile and 4,5-bis(3,3-dimethyl-1-butynyl)phthalonitrile gave 4,5-dipentylphthalonitrile and 4,5-bis(3,3-dimethylbutyl)phthalonitriles.
