Herein we reported an efficient palladium-catalyzed enantioselective arylation of both alkyl and aryl sulfenate anions to deliver various chiral sulfoxides in good yields (up to 98%) with excellent enantioselectivities (up to 99% ee) by the use of our developed chiral O,P-ligands (PC-Phos). PC-Phos are easily prepared in shortsteps from inexpensive commercially available starting materials. The single-crystal
Nickel catalyzed asymmetric synthesis of dienyl sulfoxides were accomplished with up to 98 % ee from both racemic allenyl carbonates and β-sulfinyl esters employing cheap Ni(II) as precatalyst. Experimental and computational methods revealed an interesting associated outersphere mechanism which is uncommon in transition metal catalyzed asymmetric allylic nucleophilic substitution reactions.
