Two-component metal-free catalytic oxidative sulfenylation of pyrazolones with thiols has been achieved using the biomimetic flavin and iodine. The methodology is mild and eco-friendly, proceeds in the presence of air or molecular oxygen (1 atm) as the sole sacrificial reagent, and generates water as the only byproduct. The methodology was also extended to the sulfenylation of pyrazoles and electron-rich benzenes and afforded a series of thioethers in good yields.
