An efficient aerobic chemoselective oxidation of thiols to disulfides has been achieved under ball-milling over neutral aluminium oxide (grinding auxiliary) in the absence of any catalyst, co-oxidant, solvent, or base. A wide variety of functionalized diaryl, diheteroaryl and dialkyl disulfides have been obtained in high yields.
