A novelthree-componentreaction between 1-substitutedimidazoles, aldehydes, and electron-deficientacetylenes proceeds under mild conditions (20―25 °C, no catalyst, no solvent) to form an unknown family of C2-functionalized imidazoles in up to 74 % yield, the function constituting a push-pull combination of enol ether and acrylic moieties. In the case of cyanophenylacetylene, the function is built
