Cl using organic dye eosin Y as the photocatalyst is reported. The reaction proceeds smoothly with excellent stereoselectivity via atom transfer radical addition to afford multifunctionalized bicyclic alkenyl sulfonyl fluorides. Downstream reactions of the resulting bicyclic products showcase an efficient approach to access diverse functionalized sulfonyl fluorides from readily available phenols.
