Abstract
Lithium tri-tert-butoxyaluminohydride (LTBA), an exceptionally mild reducing agent in organic synthesis, reduces functionalized aromatic disulfides to the corresponding thiols in quantitative yield. The reaction is rapid (for example, o-tolyl disulfide is reduced to completion in 60 min at 25" C) and can tolerate a wide variety of functional groups, such as halogen, nitro, carboxylic acid, and their derivatives. The presence of electron- ...
