An efficient procedure for 2-sulfolmethyl quinoline preparation from 2-methylquinolines and sodium sulfinates under transition-metal free conditions is described. Halogen functional groups were well tolerated to give the corresponding products in good to high yields.

A tetrabutylammonium iodide (TBAI)-catalyzed method for synthesis of 2-sulfolmethyl quinolone has been developed. Using water as solvent, a wide range of 2-sulfolmethyl quinolones were obtained in high to excellent yield. In addition, water and TBAI could be reused for five times without significant decrease of the yield of the corresponding product.
