Abstract (en)
[origin: WO2005003133A2] The invention relates to a method for producing the alkoxy-substituted metalliferous phthalocyanins of formula (I), wherein R represents an optionally substituted alkyl or cycloalkyl, M represents a bivalent metal atom, metalloxy, or a trivalent or tetravalent substituted metal atom. The inventive method is characterized by reacting the phthalodinitril of formula (II) in the presence of a metal salt and a base in a water-miscible solvent.
