A catalyst and additive‐free strategy for selective ring‐opening selenocyanation of saturated heterocycles with elemental selenium and TMSCN is developed, affording a series of aliphatic selenocyanates and selenaheterocycles. In the case of unprotected unstrained N‐heterocycles, the reactions offer ammonium selenonitriles that prove to be an efficient selenonitrile reagent.
