Synthesis of sulfinamides
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 aryl halides was accomplished to give N-aryl tert-butanesulfinamide without racemization, and the coupling of racemic p-toluenesulfinamide smoothly afforded N-aryl p-toluenesulfinamides. Addition of a small amount of water to the catalytic system was of importance to obtain high yields.
