Visible Light-Driven Atom Transfer Radical Addition to Olefins using Bi2 O3 as Photocatalyst.
Bismuth oxide, an inexpensive and non-toxic semiconductor, has been successfully used as a visible light photocatalyst for the atom transfer radical addition (ATRA) reaction of organobromides to diversely functionalized terminal olefins. The reaction takes place under very mild conditions, in the absence of any additive, and with low catalyst loading (1 mol %). The corresponding ATRA products are obtained with moderate to excellent yields (up to 95 %).
