Cobalt(II) phthalocyanine covalently anchored to cellulose as a recoverable and efficient catalyst for the aerobic oxidation of alkyl arenes and alcohols

• Cobalt(II) phthalocyanine covalently immobilized on cellulose as a heterogeneous catalyst was synthesized.
• Cobalt(II) phthalocyanine oxidized alkyl arenes and alcohols.
• Oxidation was proceeded under mild reaction conditions.
• Catalyst recycled for several times without significant decrease in catalytic activity.

Cobalt(II) phthalocyanine covalently immobilized on cellulose as a heterogeneous catalyst was synthesized and characterized. The catalyst showed good catalytic activity for the aerobic oxidation of alkyl arenes and alcohols under relatively mild reaction conditions. The catalyst can readily be recovered from the reaction mixture and reused for several runs without significant decrease in catalytic activity.
