Fig. 1: Strategies for the dehydrogenative alkenylation of alkanes and aldehydes with alkenes.
From: Photoinduced site-selective alkenylation of alkanes and aldehydes with aryl alkenes
a Auxiliary-assisted alkenylation. b Auxiliary-free alkenylation. c Merging of a hydrogen atom transfer photocatalyst and a cobaloxime catalyst enables site-selective direct alkenylation of C–H substrates.
