PHOTOCATALYST-FREE, LIGHT-INDUCED CARBON-SULFUR CROSS-COUPLING METHODS

In one aspect, the invention provides a method of promoting a carbon-sulfur bond forming reaction. In certain embodiments, the reaction comprises cross-coupling of a(n) (hetero)aryl halide with a thiol to form the carbon-sulfur bond, wherein the method is promoted by light irradiation in the absence of a photocatalyst. In other embodiments, the cross-coupling reaction can be promoted through visible light irradiation, including sunlight.

Visible-light-promoted C-S cross-coupling via intermolecular charge transfer

Disclosed is a mild, scalable, visible-lightpromoted cross-coupling reaction between thiols and aryl halides for the construction of C-S bonds in the absence of both transition metal and photoredox catalysts. The scope of aryl halides and thiol partners includes over 60 examples and therefore provides an entry point into various aryl thioether building blocks of pharmaceutical interest. Furthermore, to demonstrate its utility, this C-S coupling protocol was applied in drug synthesis and latestage modifications of active pharmaceutical ingredients. UV-vis spectroscopy and time-dependent density functional theory calculations suggest that visible-lightpromoted intermolecular charge transfer within the thiolate-aryl halide electron donor-acceptor complex permits the reactivity in the absence of catalyst.

Recyclable heterogeneous supported copper-catalyzed coupling of thiols with aryl halides: base-controlled differential arylthiolation of bromoiodobenzenes

Alumina-supported copper sulfate efficiently catalyzes the 5-arylation of aromatic, heteroaromatic and aliphatic thiols with aryl as well as heteroaryl halides under aerobic, ligand-free conditions. This protocol provides an easy access to a variety of thioethers as well as unsymmetrical bis-thioethers by base-controlled differential coupling of thiols with iodo- and bromo-substituents in an aromatic halide. The catalyst is inexpensive, non-air sensitive, environmentally friendly and recyclable.
