Organic Sulfur Compounds, XXXVI. Synthesis of 1,3‐Oxathioles from Monothiobenzils and Diaryldiazomethanes Four 4,4′‐disubstituted monothiobenzils 2a–d have been synthesized. They react with diaryl‐substituted diazomethanes 3a–c in solution to form tetraaryl‐substituted 1,3‐oxathioles 4a–g accompanied by evolution of nitrogen. The 1,3‐oxathioles 4a and d have been oxidized with m ‐chloroperbenzoic acid furnishing the corresponding S ‐oxides 5a and b .
