## Abstract A series of 2,2‐disubstituted 5,6‐diphenyl‐4H‐1,3‐oxathiin‐4‐ones was synthesized by cycloaddition of thiones with benzoylphenylketene, which was generated by the thermal Wolff rearrangement of 2‐diazo‐1,3‐diphenyl‐1,3‐propanedione. © 2001 John Wiley & Sons, Inc. Heteroatom Chem 12:630–
