Abstract: A visible-light organophotoredox-catalyzed sulfurization of alkenes and alkynes with aromatic and heteroaromatic thiols using eco-friendly air (O2) as the sole oxidant has been demonstrated. The established method delivers a novel, benign, and metal-free strategy for… read more here.

DOI: 10.1021/jacs.9b12335
Abstract: This manuscript reports a visible light-mediated organosul-fide catalysis that enables the decarboxylative coupling between simple aliphatic alcohol and tertiary or secondary alkyl carboxylic acid-derived redox active esters to produce a C(sp3)-O-C(sp3) fragment. Results of the… read more here.

DOI: 10.1039/d1qo00170a
Abstract: An organophotoredox-catalyzed reduction/addition/oxidation cascade of N-protected maleimides and N-(acyloxy)phthalimides is documented. The mild and efficient redox-neutral process involves the hitherto unknown Giese-type addition of aryloxy-alkyl radicals on N-protected maleimides and a successive oxidation allowing an… read more here.
