Visible-light-induced deboronative alkylarylation of acrylamides with organoboronic acids.

A visible-light-induced deboronative alkylarylation of acrylamides with organoboronic acids was developed. In this transformation, boronic acids could be activated by the organic photocatalyst of eosin Y, generating alky free radicals in high efficiency. A broad range of substrate scope was examined and a number of 3,3-disubstituted oxindoles were synthesized in high yields.
