Photoinduced Functionalization of <i>p‐/o</i> ‐Quinone Methides

Abstract Quinone methides (QMs) are highly reactive intermediates and important building blocks for diverse molecular scaffolds. In recent years, there has been remarkable growth in the area of quinone methide photochemistry. Under photoirradiation conditions, p ‐quinone methides ( p ‐QMs) exhibit versatile chemical reactivity as electrophilic acceptors for radical addition and annulation reactions. However, o ‐quinone methides ( o ‐QMs) are mostly involved in photocyclization reactions. This review sheds light on recent advancements (2020–mid 2025) in photoinduced functionalization of p‐/o ‐quinone methides to form diverse molecular scaffolds, especially emphasizing their mechanistic insights.
