The present invention provides a bio-electrode composition capable of forming a living body contact layer for a bio-electrode that is excellent in conductivity and biocompatibility, is light-weight, can be manufactured at low cost, and can control significant reduction in conductivity even though the bio-electrode is soaked in water or dried. The present invention is accomplished by a bio-electrode composition including an ionic material and a resin, in which the ionic material is a lithium salt, a sodium salt, a potassium salt, a calcium salt, or an ammonium salt of sulphonamide represented by the following general formula (1).
[R1—C(═O)—N−—SO2—Rf1]nMn+ (1)
carbodiimides RN=C=NSO2CF3 are formed in high yield. In other words, an aza Curtiusrearrangement occurs. The carbodiimides react with water, alcohols, and secondary amines to give corresponding ureas, isoureas, and guanidine derivatives. Imidoyl chlorides with substituents other than SO2RF do not enter into the aza Curtius reaction.

N-Sulfonylcarboxamides can act as both a directinggroup for C–H activation and an internal oxidant in the Ru-catalyzedannulation reaction with alkynes to give isoquinolones. Of all of the N-sulfonylcarboxamides that were studied, the N-(2,6-difluorophenyl)sulfonamide derivatives were found to be the most efficient and led to the formation of an unstable sulfinate byproduct that decomposed into 1
