Acylsilanes are able to react as nucleophilic carbene precursors, electrophiles, and directing groups in C–H functionalization. To date, some of the products reportedly formed during transition-metal-catalyzed and photochemical reactions involving acylsilanes have been incorrectly assigned. To provide clarity, we herein address these structural misassignments and detail the revised structures. New
