α,α′-Dioxothione 1a and ortho-thioquinones 2a and 2b are able to react with several phenols and N,N-dimethylaniline to give the corresponding alkyl aryl or diaryl sulfides. The mechanism of this reaction was proved to be an electrophilic aromatic substitution undergone by the highly polarised carbon−sulfur double bond. Following this procedure, the atropoisomeric biphenyl compound 26 was also prepared
