Catalyst-free direct C-H selenoxylation of (hetero)arenes

Key Points

• To explore the application of Se(IV)-based electrophiles in the direct C-H selenoxylation of (hetero)arenes.
• Used arylseleninic acids as electrophiles
• Conducted experiments in a catalyst-free environment
• Focused on the synthesis of selenides from (hetero)arenes
• Successfully performed C-H selenoxylation without a catalyst
• Demonstrated the effectiveness of Se(IV)-based electrophiles in the reaction
• Produced a range of selenides with high efficiency
