4‐Aryl‐2‐Imino‐1,3‐Dithiolanes from the Room Temperature Coupling of Sodium Dithiocarbamates with Sulfonium Salts.

A series of 4‐aryl‐2‐imino‐1,3‐dithiolanes was synthesized by means of a straightforward strategy starting from readily available precursors: reactions of dithiocarbamates and arylsulfonium salts, at room temperature in water/CH2Cl2 as biphasic medium, afforded the five‐membered cyclic products in good yields. The reaction mechanism was investigated by DFT calculations. [ABSTRACT FROM AUTHOR]
