development of novel luminescentiridium(III) complexes with highly tunable emission energy and versatile applications is of particular importance. In this Communication, a series of luminescentiridium(III) complexes supported by chromophoric pyridinium-derived N-heterocyclic carbene (NHC) ligands that display tunable emission from 516 to 682 nm were prepared. These complexes can be used as photocatalysts

We describe the anti-Markovnikov hydrothiolation of olefins using visible-light-absorbing transitionmetal photocatalysts. The key thiyl radical intermediates are generated upon quenching of photoexcited Ru*(bpz)32 with a variety of thiols. The adducts of a wide variety of olefins and thiols are formed in excellent yield (73–99%).

for an anti-Markovnikov hydrothiolation of unactivated olefins using benzophenone as an inexpensive photocatalyst at room temperature. Anti-Markovnikov adducts of a wide variety of olefins and thiols are formed in highly regioselective manner and good to excellent yields. The present radical thiol-ene reaction is operationally simple and well tolerates a variety of functional groups.
