Styrylcyanines based on protocatechuic aldehyde
Catechols are interesting and promising research objects in biomedical, organic, and inorganic chemistry. Their derivatives show biological activity as dyes, complexing agents, etc. We have found that catechol and its halide derivatives, protocatechuic aldehyde react with zirconium and hafnium phthalocyaninate dichloride by ligand exchange reactions to form the corresponding derivatives [1,2]. This work aimed to investigate the interaction between protocatechuic aldehyde and activated indolenines of the different structures under the conditions of the Knevenagel condensation reaction.
