Skeletal Editing of Cyclic Molecules Using Nitrenes

Comprehensive Summary Nitrenes, as neutral monovalent nitrogen‐centered molecular species, can insert into various bond or remove nitrogen atoms from amines. Nitrene assisted single‐atom skeletal editing, discovered decades ago, provides an efficient approach for the precise alteration of cyclic skeletons. In this review, we briefly summarize early studies on skeletal editing of cyclic frameworks involving nitrene species, and introduce several recent important advances systematically.
