Abstract

The reaction of a thiol with 1-chlorobenzotriazole (BtCl) affords the benzotriazolated thiol (RSBt) without appreciable formation of the symmetrical disulfide. RSBt reacts with another thiol to form the unsymmetrical disulfide in a one-pot sequence without the need for toxic and harsh oxidizing agents.
