Arylation and Vinylation of α-Diazocarbonyl Compounds with Boroxines
摘要:
An alternative approach for alpha-arylation and alpha-vinylation of carbonyl compounds is described: reaction between aryl- or vinylboroxines with alpha-diazocarbonyl compounds leads to the formation of alpha-arylated or alpha-vinylated carbonyl compounds under mild conditions.

We report a rare polarity-mismatched radical addition reactionusing styrene boronic acids and redox-active N-hydroxyphthalimide (NHPI) esters under photoredox catalysis. The reactiondisplays broad scope with mechanistic investigations supporting a unique synergistic activation pathway that displays chemoselectivity for styrene boronic acids in the presence of other SOMOphiles.
