The redox-neutral dicarbofunctionalization of tri- and tetrasubstituted olefins to form a variety of (hetero)cyclic compounds under photoinduced palladium catalysis is described. This cascade reaction process was used to couple styrenes or acryl amides with a broad range of highly decorated olefins tethered to aryl or alkyl bromides (>50 examples). This procedure enables one or two contiguous all-carbon

Direct UV irradiation of ortho-allyloxy- and ortho-but-3-enyloxy-iodo- and bromo-benzenes in the presence of NaBH4 or NaBH3CN gave radical cyclization products in high yield.
