A novel method for the formation of 2-arylsulfanylphenols fromthiols and cyclohexanones is described. Iodine was used as an effective catalyst for this kind of transformation. Cyclohexanones were used as a phenol source via a dehydrogenation and tautomerization reaction.
Some reactions of 1,3-benzoxathioles and 1,3-benzodioxoles with Grignardreagents were examined in order to verify whether or not reduction products were present in addition to the substitution and elimination products previously observed. The reaction mixtures contain reduction products whenever the Grignardreagent has β-hydrogen atoms, in which case the reagent is likely to act as a hydride transfer
