The efficient copper and triphenylphosphine-promoted sulfenylation of quinones with arylsulfonyl chlorides has been developed under mild conditions with moderate to good yields. Significantly, this provides an alternative method to synthesise arylthioquinone derivatives. This is the first time that arylthioquinones with arylsulfonyl chlorides as starting material have been prepared, which avoids the use of the awful smelling thioalcohols and thiophenols.
The convenient synthesis and reaction of 2-(arylthio)phenols under ligand-free conditions: arylthioquinone preparation through cascade C–H functionalization and oxidation from arylthiols and aryl iodides

A convenient and simple method for copper-catalyzed synthesis of 2-(arylthio)phenols through C–H functionalization of arylthiols and aryl iodides was developed under ligand-free conditions without nitrogen protection. In addition, arylthioquinone derivatives were very easily prepared for one more step of oxidation with moderate to good yields. This provide an alternative and efficient way to 2-(arylthio)phenols and arylthioquinone derivatives smoothly without using ligands and nitrogen protection or expensive arylboronic acids.
'On water': unprecedented nucleophilic substitution and addition reactions with 1,4-quinones in aqueous suspension
Tandon, Vishnu K.,Maurya, Hardesh K.
experimental part, p. 5896 - 5902 (2010/01/11)
Unique nucleophilic substitution and addition reactions of 1,4-quinones in aqueous suspension with aromatic amines, primary aliphatic amines, amino acid, ester of amino acid, heterocyclic amines, hydrazine, amide, and thioethers are described in absence o
