poisoning of the catalyst. S R A visible-light-mediated photocatalyzed protocol utilizing copper–phenanthroline-based catalysts has been developed that can convert a large number of olefins into their chlorosulfonylated products. Besides the Cu(I) complex [Cu(dap)2]Cl, now well-established in photo-ATRA processes, the corresponding Cu(II) complex [Cu(dap)Cl2] proved to be often even more efficient in the title

We have developed a direct oxidative C–H bond arylation of pyrroles with various aromatic compoundsviastabilized pyrrolyl iodonium(iii) salts generated from modified hypervalent iodine(iii) and TMSCl as an activator.
