A series of β-thio group substituted α-diazo carbonyl compounds have been prepared by nucleophilicsubstitutionreactions of thiophenol, thionaphthol, or benzyl mercaptan with β-acetoxy-α-diazo carbonyl compounds. The diazo decomposition of these diazo carbonyl compounds with various transition metal catalysts, including Rh(II) carboxylates and Cu(I) and Cu(II) complexes, has been investigated. It
