Preparation of Non-Substituted Metal Phthalocyanines at Low Temperature Using Activated<i>Rieke</i>Zinc and Magnesium

Abstract

Synthesis of non-substituted metal phthalocyaninates starting from phthalonitrile in various alcohols in presence of chemically activated Rieke zinc and magnesium in three forms (ordinary magnesium turnings, activated Rieke magnesium and complex Mg(anthracene) · 3THF) at low temperatures (20–50°C) is described. It is shown that the presence of active elemental metal causes a rapid PcM formation in low-weight alcohols.
