A perfluorinated diisocyanide was stabilized for the first time in complex 1 ( cis form is depicted). The carbon atoms of the isocyanides are susceptible to nucleophilic attack, and 1 reacts with Me 2 NH with the elimination of a [Cr(CO) 5 ] substituent to give an imidazole derivative with an annelated fluoro‐substituted four‐membered ring.
