- Chiral phosphine complexes of ruthenium(II)arenes
-
Chiral, arene-containing complexes of ruthenium(II) based on the phosphines chiraphos and diop are reported, as well as improved routes to some known analogues containing binap or the achiral phosphines Ph2P(CH2)nPPh2 (n=2, dppe; n=4, dppb).

- Synthesis of New Cationic BINAP-Ruthenium(II) Complexes and their Use in Asymmetric Hydrogenation
-
Reaction of 2 (1) and (S)-BINAP gives cationic BINAP-ruthenium complexes of the formula Y (2) (X = Cl, Br, and I; Y = Cl, Br, I, BF4, and BPh4; arene = C6H6 and p-MeC6H4CHMe2) which are efficient catalyst precursors for enantioselective hydrogenation of various prochiral alkenic and ketonic substrates ; a crystal structure of (2) (with X = Cl, Y = BF4) was obtained.
