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.

The allyl Mn(II) organic compounds R1CH = C(R2)CH2MnCl (R1 = H, Me; R2 = H, Me, Bu), obtained in situ from Grignard reagents and Li2MnCl4, react with esters of 4-bromocrotonic, (2-bromobutylidene)-, (4-bromo-2-butenylidene)-, (2-bromoisobutylidene)malonic, and (2-bromoheptylidene)cyanoacetic acids in THF at -78 to +20-degrees-C to give derivatives of substituted cyclopropanecarboxylic or cyclopropane-1,1-dicarboxylic acids. These derivatives contain a fragment of the allyl type. When ethers of 2-(bromomethyl)acrylic, 4-bromo-2-methyl-, and 4-bromo-3-methyl-2-butenoic acids are used, cross-combination products result.
