to chemically modify them and efficiently access libraries of these compounds have been goals of the highest priority in the last decades. In this work, a series of sp2–sp3 fragments was synthesized and validated for that purpose, based on their measured physical–chemical properties. Selective C–H cyanation and allylation of these fragments was demonstrated by simple heating in presence of an appropriate

spirocycles toward selective C–H functionalization reactions are scarce, despite their potential applications. In this work, we uncovered fundamental reactivity and selectivity differences between saturated heterocycles and their spirocyclic analogues using a model radical C–H xanthylation coupled with computational analysis. Ultimately, this study sheds light on the fundamental, understudied radical reactivity
