Deoxygenative Radical Addition of Aryl Carboxylic Acids to Alkenes with Phosphine in a Two-molecule Photoredox System

Key Points

• To develop a photoredox system for the deoxygenative radical addition of aryl carboxylic acids to alkenes.
• Utilized a two-molecule photoredox system
• Combined an organic photocatalyst with phosphine
• Conducted reactions under mild conditions
• Successful deoxygenative radical addition of aryl carboxylic acids to electron-deficient alkenes
• Effectiveness demonstrated under benign reaction conditions
• Cooperative action of photocatalyst and phosphine enhanced reaction efficiency
