Use of carbon-sulfur cathodes in electro-organic chemistry - Part 2 - Reactions with activated alkenes; evidence for a vicarious substitution specific of this type of electrode.

The sulfur-carbon electrode, used as a cathode, appears to be an excellent source of nucleophiles which are good sulfuration reagents towards alkenes not substituted by leaving groups.However, the electrochemical reactions are often complex.It should be w

Pyrrolo-1,3,4-thiadiazole Derivatives from Mesomeric Heteropentalenes and Azodicarboxylic Esters

The mesomeric heteropentalene betaines of type 4,7, and 18 display an unusual reaction behavior against the azodicarboxylic esters 8a-c.Surprisingly, 4 reacts with 8a,b to produce 17a,b, whereas the reaction of 4 with 8c leads to 11 and the novel azomethine imine 15.Also the reaction of 18 with 8a-c gives in two cases 20 or 25 beside the azomethine imine 19.Furthermore, 7 reacts with 8a to form 26, whereas the reaction of 7 with 8c surprisingly yields 29.Spectroscopic data as well as the results of the X-ray analyses of 17a and 19 are consistent with the structures.
