A new synthetic route of 2‐nitrothiophenes was described through a tetra‐n‐butylammonium fluoride‐promoted or diisopropylethylamine‐promoted tandem Henry reaction and nucleophilicsubstitution of nitromethane with 3‐thiocyanatopropenals, which were conveniently prepared by the replacement reaction of 3‐chloropropenals with potassium thiocyanate under a mild acidic condition.

A Useful One-Pot Procedure for Obtaining 2-Aryl-5-nitrothiophenes from Bromonitromethane and 3-Aryl-3-chloro-propenals
A one-pot procedure was developed to prepare new 2-aryl-5-nitrothiophenes efficiently from bromonitromethane and 3-chloro-3-aryl-propenals. Nitrothiophenes were synthesized in good yields with a simple and easy workup procedure.
