Catalyst tune-up: A readily available, air-stable amino–sulfide catalyst, [RuCl2(PPh3){HN(C2H4SEt)2}], has been developed. This complex displays outstanding efficiency for the hydrogenation of a broad range of substrates with C[DOUBLE BOND]X bonds (esters, ketones, imines), as well as for the acceptorless dehydrogenative coupling of ethanol to ethyl acetate (see scheme).
