摘要

Thioamides are very useful intermediates' for organic synthesis and are prepared mainly a) by the reaction of amides with phosphorous pentasulfide2 or Lawesson reagent3, b) by the Willgerodt-Kindler reaction4 and c) by the reaction of nitriles or cyanogen with hydrogen sulfide! Among these, the Wdgerodt-Kindler reaction is the better and more convenient procedure, for the preparation of thioamides from aromatic aldehydes or ketones by ...
