The easy oxygenation of triphenylphosphine is well defined in Wittig, Mitsunobu and many other reactions. This reducing agent works well in the presence of other functional groups such as nitro groups, halogens, carboxylic acids, and ketones. The ease of preparation of arylsulfonyl chlorides, together with the activity profile of triphenylphosphine, led us to develop a method for the preparation of arylthiols from the corresponding arylsulfonyl chlorides as shown in ...
