| Abstract | The novel diamine/bis(ether/phosphine)ruthenium(II) complexes Cl2Ru(h 1 -Ph2PCH2/CH2OCH3)2(diamine)2(3L1/3L11 )h ave been obtained by reaction of equimolar amounts of Cl2Ru(PS/O)2 (2) with the respective diamines L1/L11 in good yields. X-ray structural investigations of 3L2 and 3L8 show monoclinic unit cells with the space group P 21/c . The octahedrally coordinated ruthenium atoms have each two trans- chlorides and cis -phosphines which is in agreement with NMR studies in solution. With the exception of 3L4 all mentioned ruthenium complexes are highly catalytically active in the hydrogenation of the a,b-unsaturated ketone trans -4-phenyl-3-butene-2-one. In most cases the conversions and selectivities toward the formation of the unsaturated alcohol trans -4-phenyl-3-butene-2-ol were 100% with high turnover frequencies under mild conditions. # 2003 Elsevier Science B.V.
