<jats:title>Abstract</jats:title><jats:p>A systematic investigation of ethynyl <jats:italic>N</jats:italic>‐heterocycle‐substituted‐λ<jats:sup>3</jats:sup>‐iodanes (ENHIs) is presented. In a straightforward one‐pot synthesis these novel reagents can be obtained in high yields bearing a variety of <jats:italic>N</jats:italic>‐heterocycles. Their reactivity as electrophilic alkyne group transfer reagents was benchmarked in well‐established and novel inter‐ and intramolecular group transfer reactions.</jats:p>
