REACTION OF 2-BENZOYL- AND 2-NITROETHENE-1,1-DITHIOLATES WITH DIMETHYL ACETYLENEDICARBOXYLATE

The reaction of dimethyl acetylenedicarboxylate with 2-benzoyl- and 2-nitroethene-1,1-dithiolates leads to 2-alkylidene-4,5-dimethoxycarbonyl-1,3-dithiolanes (in the form of an equilibrium mixture of the trans and cis isomers).A series of side products are also formed under the reaction conditions. 2,3,4,5-Tetramethoxycarbonylthiophene and 3,5-di(benzoylmethylene)-1,2,4-trithiolane were identified among them.
