A visible-light initiated oxidative cyclization of phenyl propiolates with sulfinic acids has been developed at room temperature under metal-free conditions.
A novel and efficient TBHP/I2-promoted oxidative coupling reaction of acetophenones with amines for the synthesis of α-ketoamides has been developed. The reactions proceeded smoothly at room temperature under metal-free and solvent-free conditions and generated the corresponding products in good yields.
