Abstract

The preparation of phthalocyanines are difficult because of their poor reactivity of reactants. In order to improve the reactivity, safety, and green technology in the preparation of the phthalocyanine (4-tBuPcH₂), several types of ionic liquids were applied as reaction medium. In the case of using [C₂-OHm₂im][Br] as a reaction media, 4-tBuPcH₂ was obtained in the highest yield (38%). These results suggested that the hydroxy groups, anion species, and stability of cations of ionic liquids are important to synthesis of 4-tBuPcH₂. In addition, [C₂-OHm₂im][Br] was reused without any loss of its catalytic activity.
