a Incorporation of B–N, PV=N, and SVI=N bonds. b Sulfoximine and sulfondiimine as aza-analogs of sulfone. c Challenges in the Pd-catalyzed C–H activation of S=N-containing compounds. d Pd-catalyzed enantioselective desymmetrization of diaryl sulfoximines and sulfondiimines involving split (acyclic) and combined (cyclic) aromatics (this work).
