Visible-Light-Mediated Reactions of Electrophilic Radicals with Vinyl and Allyl Trifluoroborates

Visible-light photoredox catalysis enables the vinylation and allylation of electrophilic radicals with readily available potassium trifluoroborate reagents. The processes show good functional group compatibility, and mechanistic and computational studies have elucidated some of the aspects associated with the key radical addition step.
