The synthesis of transition-metal phthalocyanines by the reaction of substituted and unsubstituted phthalonitriles in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and metal salts in functional imidazolium, pyridinium and ammonium ionic liquids at 100-140 °C, is reported. The best yields of metallated phthalocyanines were achieved in butyl(2-hydroxyethyl)dimethylammonium bromide ionic liquid. Metallation of free-base phthalocyanines with different metal salts in the above ionic liquid has also been achieved in good yields.

ammonium ionicliquids at 100 °C gave corresponding phthalocyanines in moderate yield. Further the reaction of substituted phthalonitriles in the presence of transition-metal salts in ionicliquids gave the corresponding metallophthalocyanines. The 2-hydroxylethyl ammonium ionicliquids gave better yields of phthalocyanines than 2-hydroxylethyl imidazolium and nonhydroxyl functionalized ionicliquids. The
摘要 在任务特定的 2-羟乙基基咪唑鎓和铵离子液体中,取代的邻苯二甲腈在 100 °C 下四聚化,以中等产率得到相应的酞菁。此外,在过渡金属盐的存在下,取代的邻苯二甲腈在离子液体中的反应得到相应的金属酞菁。2-羟乙基铵离子液体比2-羟乙基咪唑鎓和非羟基官能化离子液体产生更好的酞菁收率。不同酞菁的分离和分离采用硅胶柱色谱法完成,产物采用多种光谱技术进行表征。图形概要
A new strategy for inducing dipole moments in charge-transfer complexes: introduction of asymmetry into axially ligated iron phthalocyanines
Introduction of asymmetry into charge-transfer complexes composed of axially ligated iron phthalocyanines was achieved. In the obtained crystals of TPP[FeIII(Pc)(CN)Cl]2, TPP[FeIII(Pc)(CN)Br]2, and TPP[FeIII(Pc)BrCl]2 (TPP = tetraphenylphosphonium and Pc = phthalocyanine), the axial positions of the iron atoms were occupied by 50/50 ratios of the ligands CN/Cl, CN/Br, and Br/Cl, respectively. The crystal

Metallophthalocyanine complexes are obtained quickly and efficiently by the reaction of phthalodinitrile with hydrated metallic salts without solvent and under microwaveirradiation. The use of a modified commercial microwave oven to perform this type of reactions under dry conditions is described. Metallophthalocyanines and metallododecachlorophthalocyanines of some divalent metals can be also obtained
