In recent publications we have discussed the mechanistic aspects of the cycloaddition-elimi-2 nation reactions of 1,2,3,4-thiatriazoline-5-imines 1 with isothiocyanates, isocyanates and electrophilic nitriles. Rased on the knowledge gained from these experiments we expect that the reactions of 1 wit

## Abstract A novel three‐component reaction between 1‐substituted imidazoles, aldehydes, and electron‐deficient acetylenes 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 p
