Abstract: | On Chalcogenolates. 136. Alkyl Esters of Cyanoformic Acid and of Cyanomonothioformic Acid By use of the phase transfer catalyst 18-crown-6 the esters CH3O—CO—CN, C2H5O—CO—CN, C2H5S—CO—CN, and nC3H7S—CO—CN have been prepared by reaction of the corresponding chloro compound with potassium cyanide. The prepared compounds have been characterized by means of electron absorption, infrared, nuclear magnetic resonance (1H and 13C), and mass spectra. |
