STUDY OF THE MECHANISM OF RECYCLIZATION OF FURANS TO THIOPHENES AND SELENOPHENES UNDER THE CONDITIONS OF ACID CATALYSIS. 7. THE EFFECT OF THE NATURE OF THE NUCLEOPHILE. THE COMPETITION CONSTANT
Kinetic investigations into the reactions of 2,5-dimethylfuran with mixtures of hydrogen sulfide and selenide in various quantitative ratios were undertaken, and the competition constant was determined. This made it possible to correlate numerically the nucleophilicity of hydrogen sulfide and selenide in the reaction.
