    摘要: Aminoacetonitrile derivatives, where the 2-position of aminoacetonitrile is optionally substituted by alkylthio groups, arylthio groups and heterocyclicthio groups. The process for making such compounds comprises reacting hydrogen cyanide with the desired corresponding R-S-H and recovering the crystallized salt thereof. The aminoacetonitrile derivatives are useful as starting materials to produce pharmaceutical and agricultural intermediates such as benzomide derivatives with fungicidal and herbicidal activities.
