Abstract
Sulfonylated N-unsubstituted enamines were synthesized through a chain of chemical and electrochemical transformations via sulfonylation of vinyl azides. The disclosing of the N-unsubstituted enamines synthesis was based on a unique property of the azido group, which is its ability to eliminate the N2 molecule. Furthermore, a formal paradox is observed: a double bond reacts and a double bond is retained. Electrosynthesis proceeded in an undivided cell equipped with a graphite anode and a stainless steel cathode; NH4I was used as a supporting electrolyte.
