Abstract
A new and efficient solid‐state method for the preparation of thiohydantoins is reported. With this method, twelve thiohydantoin compounds have been synthesized in good to excellent yields (81–92%). In addition, this method has the advantages of high yields, a cleaner reaction, simple methodology, and short reaction times.
