Desaturative arylaldehyde synthesis by synergistic carbocatalysis and organocatalysis

Key Points

• The aim is to develop a cooperative catalytic system for transforming cyclohexene aldehydes into aromatic aldehydes.
• Utilized a metal-free cooperative system involving carbocatalysis and organocatalysis.
• Employed quinone-rich oxidized activated carbon as the carbocatalyst.
• Incorporated secondary amines as the organocatalyst.
• Successfully transformed 3-cyclohexene aldehydes to aromatic aldehydes.
• Achieved a diverse range of substrates indicating broad applicability.
