Just click with silver: Pyrroles are prepared by the co‐cyclization of terminal alkynes and isocyanides in a silver‐catalyzed click reaction. This route represents an extremely simple, efficient, and atom‐economic approach to substituted pyrroles in good yields with high selectivity, thus complementing the click method for the rapid formation of multifunctional heterocycles.
