(Equation Presented) A new method for the synthesis of thiocarbamates has been developed. When dialkyl or diaryl disulfides were allowed to react with secondary amines and carbon monoxide in the presence of a catalytic amount of a palladium complex, the thiocarbamates were obtained in moderate to good yields. In contrast to that of secondary amines, in the reaction of a primary amine, no formation of thiocarbamate was confirmed, but urea was formed in good yield.

The reaction of 2-methylthiophenol with sodium hydride and N,N-diethylcarbamyl chloride in THF afforded N,N-diethylthiocarbamic acid S-o-tolyl ester in 97% yield. The ester was subsequently treated with LDA and various aromatic aldehydes to provide new 3-
