A catalytic β-selective addition of amines to styrenes proceeded in the presence of cationic Ru complexes combined with diphosphine ligands. In the reaction of α-methylstyrene, an enantioselective addition was achieved by using xylylBINAP.

Catalytic S N Ar reaction of fluoroarenes possessing no electron-withdrawing group(s) with cyclic amines was achieved using a readily accessible Ru catalyst, which was prepared from [Ru(benzene)Cl 2 ] 2 , AgOTf, and P(p-FC 6 H 4 ) 3 . The coexistence of molecular sieves MS4A realized high conversion and various substituted aryl amines were obtained in good to high yields.
