Phthalocyanines@ magnetic chitosan: As an efficient nanocatalyst for selective aerobic oxidation of alkyl arenes and alcohols

Oxidation is the second largest industrial process that plays an important role in organic chemistry [1]. The synthesis of the valuable oxygen-containing compounds (ketones, aldehydes, esters, and acids) from hydrocarbons in the aerobic oxidation conditions is an important challenge for the chemical industry and a large number of homogeneous and heterogeneous catalytic systems have been developed for aerobic oxidation processes. Phthalocyanines (PCs) are important compounds that have attracted considerable attention due to their excellent properties and have many applications in dye-synthesized solar cells, photodynamic therapy, pigments, dyes, and biomimetic catalyst. Various supports such as silica, activated carbon, metal-organic frameworks and biopolymers as a support have been used for immobilization the phthalocyanines [2]. Recently, we have showed that phthalocayanines immobilized onto graphen and cellulose were efficient catalysts for organic transformations. Within our program on sustainable organic transformations and nanocatalyst [3], we have introduced the phthalocyanines@ magnetic chitosan as an efficient nanocatalyst for an aerobic oxidation of various alkyl arenes and alcohols.
