Functionalization Of Benzylic Sp(3) C-H Of 2-Methylazaarenes In Deep Eutectic Solvent

The catalyst-free addition of 2-methylazaarene benzylic sp(3) C-H to electron-deficient olefins in deep eutectic solvents is reported. Moderate to good yields were obtained in 2 h at 80 degrees C in deep eutectic solvents. The method was operationally easy and involved mild reaction conditions. This expands the application of deep eutectic solvent in sp(3) C-H functionalization reaction.
