Abstract—: Two synthetic approaches for obtaining of zirconium and hafnium dihydroxophthalocyaninates (i.e. (a) that using the zirconium and hafnium alkoxides as the reactive precursors and (b) hydrolysis of zirconium and hafnium dichloridophthalocyaninates) were evaluated. Reactivity of zirconium and hafnium dihydroxophthalocyaninates in their exchange reactions with β-diketones and with decanoic acid was also studied; they were compared with those of zirconium and hafnium dichloridophthalocyaninates. The use of zirconium and hafnium dihydroxophthalocyaninates as the precursors in their reactions with acid-sensitive ligands, such as ketoesters, is found to be a more effective approach.

The series of new zirconium(IV) and hafnium(IV) phthalocyanines with various β-dicarbonyl ligands were prepared via direct interaction between di(chloro)zirconium(IV) or hafnium(IV) phthalocyanines and free β-diketones and also with 4-benzoyl-3-methyl-1-p
