Notes:
The synthesis of highly soluble chloro(phthalocyaninato)indium(III) complexes RxPcInCl (3a: R1 = tert-butyl, R2 = H, x = 4 and 4a: R1 = R2 = n-pentyl, x = 8), and their reactions with R′MgBr [R′ = p-trifluoromethylphenyl- (b), m-trifluoromethylphenyl- (c), p-fluorophenyl- (d), perfluorophenyl- (e)] leading to the stable σ-bonded aryl(phthalocyaninato)indium(III) complexes 3b-e, 4b-e are described. All compounds were characterized by IR, UV/Vis, MS, 1H, 13C and 19F NMR as well as elemental analyses. Phenyl(phthalocyaninato)indium(III) (4f) was prepared by the reaction of (n-C5H11)8PcInCl (4a) with PhLi. The high solubility of the complexes 3a-e and 4a-f is, aside from the influence of the peripheral substituents, considered to be derived from the large dipole moments present which are due to the strongly electron withdrawing axial ligands, and from the lower tendency of axially substituted phthalocyaninato metal complexes to form aggregates.
