Abstract
Transformation of several 1-(2-benzimidazol-2-ylethyl) pyridinium salts, obtained by two different procedures, into their corresponding 2-vinylbenzimidazoles either using an anion- exchange resin (OH-form) or in the solid state is described. This approach now allows a facile entry into the almost unknown 2-vinylbenzimidazole monomers.
