Paragraph 00107, (2014/02/16)
In some embodiments, the present disclosure pertains to a compound, comprising a transition metal complex having the formula Φ-[Μ (x,y)-L1 (w,v)-L2 (t,u)-L3]p+An-mZ-p_m. In an embodiment of the present disclosure Φ may be A. In another embodiment Φ may be Δ. In some embodiments of the present disclosure, M is a transition metal. In a related embodiment, p is an integer corresponding to the oxidation state of M. In some embodiments of the present disclosure, each of x, y, w, v, t, and u independently comprise R. In other embodiments, each of x, y, w, v, t, and u independently comprise S. In an embodiment of the present disclosure, each of L1, L2, and L3 independently is a ligand comprising a substituted diamine. In some embodiments, An" comprises a lipophilic anion, where m is from 1 to 3, and where Z- comprises an optional second anion.

Page/Page column 8, (2008/06/13)
A diamine of formula (I) is described, in which A is hydrogen or a saturated or unsaturated C1-C20 alkyl group or an aryl group; B is a substituted or unsubstituted C1-C20 alkyl, cycloalkyl, alkaryl, alkaryl or aryl group or an alkylamino group and at least one of X1, X2, Y1, Y2 or Z is a C1-C10 alkyl, cycloalkyl, alkaryl, aralkyl or alkoxy substituting group. The chiral diamine may be used to prepare catalysts suitable for use in transfer hydrogenation reactions.
