Alkali-metal 2-arylethynethiolates react with alkyl phenylpropiolates differently, depending on the nature of the cation.The lithium salt form 1,3-anionic cycloaddition product, i.e., alkyl 2,4-diaryl-3-thiophenecarboxylate.The potassium salt enters into a nucleophilic addition reaction at the triple bond of the ester to form the E-3-(2-arylethynylthio)-3-propenoic ester.The corresponding 1,4-dithiafulvenes are side products.
