The palladium(0)-catalyzed reactions of the primary and secondary allylic sulfoximines 7, 9, 11, 13, 15, 17, and 19 gives allylic sulfinamides without 1,3-allylic rearrangement. These compounds were not isolated but were converted to their corresponding N-tosyl allylic amines, primary and secondary 8, 10, 12, 14, 16, 18, and 20, respectively. In the case of the optically active secondary allylic sulfoximines 17 and 19, chiral N-tosyl allylic secondary amines were formed in high enantiomeric purities.
