Heterocyclic Betaines. Novel Ethyleneimidazolium Benzimidazolate Inner Salts. Synthesis, Characterization, and Transformation into 2-Vinyl-1H-benzimidazoles

The first synthesis of the hitherto unknown ethyleneimidazolium benzimidazolate inner salts is described.Their dipolar structure is well reflected on the basis of the 1H and 13C NMR parameters.Under neutral and mild conditions the title compounds underwent a type of β-elimination, affording their corresponding 2-vinyl-1H-benzimidazoles in high yields.

An Efficient Synthesis of 2-Vinylbenzimidazoles from 1-(2-Benzimidazole-2-ylethyl)pyridinium Salts Using an Anion-Exchange Resin

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.
