Synthesis of dichloro Phthalocyaninato complexes of Titanium, Zirconium, and Hafnium

A new approach to the synthesis of dichloro phthalocyaninato complexes of titanium, zirconium, and hafnium was developed. The hydrolytic stability of the compounds synthesized was studied. All complexes were characterizedby elemental analyses and IR and electronic absorption spectra.
