Abstract
Reaction of 12 secondary amines and trimethylamine with (Z) and (E)-5-nitro-2-furylvinyl bromide (I) was studied. Whereas the enamines II, obtained from secondary amines, have the E configuration, the quaternisation of trimethylamine affords stereospecifically the corresponding (Z) or (E) vinylammonium salts III.
