The palladium-catalyzed C–N cross coupling of sulfinamides and arylhalides is reported. In the presence of Pd2(dba)3, tBuXPhos, NaOH, and a small amount of water, the C–N cross coupling of chiral tert-butanesulfinamide and arylhalides was accomplished to give N-aryl tert-butanesulfinamide without racemization, and the coupling of racemic p-toluenesulfinamide smoothly afforded N-aryl p-toluenesulfinamides

An efficient kineticresolution of sulfinamides via an asymmetric N-allylic alkylation reaction was realized using hydroquinine as a catalyst under mild conditions. The kineticresolution of a range of Morita–Baylis–Hillman adducts and N-aryl tert-butylsulfinamides was highly effective. In addition, the synthetic utility of the protocol was demonstrated by a scaled-up reaction. Density functional theory

An asymmetric synthesis of N-aryl sulfinamides was achieved through copper-catalyzed coupling reactions of aryl iodides with sulfinamides. Such a kinetic resolution process provided the desired coupling products in moderate to good yields and with moderate enantioselectivities.
