Abstract
2-Cyano-2-(hydroxyimino)dithioacetic acid was prepared starting from cyanoacetic acid methylester via 2-cyano-2-(hydroxyimino)acetic acid methylester. Before thionation, the ester had to be hydrolyzed. The optimum conditions for each reaction were identified. P4S10 was found to be the efficient thionation reactant resulting in the formation of the dithionated product. Its structure was verified with IR, NMR and mass spectrometric measurements.
