Abstract
N,N-disubstituted thioamides are prepared by contacting N,N-disubstituted amides with carbon disulfide or carbon oxysulfide under suitable reaction conditions. In a preferred embodiment, the reactants are contacted at a temperature of at least about 200.degree. C and a pressure sufficient to maintain the reactants in the liquid phase at the reaction temperature.
