AbstractThe palladium-catalysed Suzuki–Miyaura cross-coupling reaction of organohalides and organoborons is a reliable method for carbon–carbon bond formation. This reaction involves a base-mediated transmetalation process, but the presence of a base also promotes competitive protodeborylation. Herein, we established a Suzuki–Miyaura cross-coupling reaction via Lewis acid-mediated transmetalation of an organopalladium(II) intermediate with organoborons. Experimental and theoretical investigations indicate that the controlled release of the transmetalation-active intermediate enables base-independent transmetalation under heating conditions and enhances the applicable scope of this process. This system enables us to avoid the addition of a traditional base and, thus, renders substrates with base-sensitive moieties available. Results from this research further expand the overall utility of cross-coupling chemistry.

High Yields

A mild, scalable iodine-mediated oxidative cross-coupling reaction of arylhydrazines and thiols for construction of thioethers (sulfides) in the absence of any transition metals or photocatalysts is disclosed. A variety of unsymmetrical diaryl sulfides with broad substrate scope both on thiols and hydrazines were synthesized in high yields in water at room temperature. Furthermore, to demonstrate the utility of the protocol, the above C–S bond formation was applied in the synthesis of the key structure of vortioxetine as an antidepressant drug. The gram-scale outcome also added to the potential utility of this protocol.

Cross Coupling Reaction

NiCl2(PPh3)2-catalyzed alkylative olefinations of trithioorthoesters and tetrathioorthocarbonates give the corresponding substituted alkenes. Aliphatic C - S bonds in these substrates can be activated in the nickel-catalyzed cross coupling reaction leading to carbon - carbon bond formation. This reaction can be considered as using trithioorthoesters and tetrathioorthocarbonate as R3C3+ and C4+ synthons.
