time: Cyanocarbenes have been formed by the reaction of azides with hypervalentiodoniumalkynyltriflates (HIATs). Experimental evidence supports the potential intermediacy of an azide‐substituted vinylidene or alkynylazide, both of which could form a cyanocarbene. Trapping of the vinylidene and cyanocarbene includes OH insertion, dimethyl sulfoxide coordination, and cyclopropanation reactions.
