The f -addition of NH-acids such as pyrrole, indole, imidazole, or benzimidazole to methyl or ethyl propiolate proceeds under neutral conditions in the presence of a catalytic amount of triphenylphosphine to give the corresponding f -substituted alkyl acrylates.
present the synthesis and characterization of poly(ethyl 2-(imidazol-1-yl)acrylate) (PEImA) using free radical polymerization in various solvents with and without acids as additive. In addition, PEImA was also prepared using anionic polymerization with KOtBu as initiator in DMF and in THF at different M:I ratios. The resulting polymers of moderate dispersity were characterized by 1H-NMR, solidstate 13C-NMR
