Acetamide → 2,6-Xylyl isothiocyanate

참여 물질

반응 단계

Briefly, this preparation involves first adding the acetamide to a suspension of sodium hydride in an organic solvent, preferably a N,N-dimethylacetamide/benzene solvent system. The cessation of hydrogen indicates completion of the reaction after which the reaction mixture is cooled and carbon disulfide added slowly. When tetrahydrofuran is the solvent employed, a reaction time of approximately 1.5 hours is required to provide yields in excess of 80 percent while when a mixture of N,N-dimethylacetamide/toluene is used, yields in excess of 80 percent are obtained in approximately 20 minutes.
