运动会班级入场词摘要：Dihalo-bis-(diphosphine) -diiridium (I) complexes (I) are new. Also claimed are methods for the preparation of optically active amines (II) and indolines (V) by (I)-catalyd hydro-amination. Iridium (I) phosphine complexes of formula (I) (specifically in solid form) are new. X = F, Cl, Br or I; L-L' = chiral bidentate diphosphine ligand, including cis-/trans-isomers and isomer mixtures. Independent claims are included for: (i) the preparation of (I); (ii) the preparation of optically active amines of formula (II) by reaction of an olefin of formula (III) (or the corresponding trans-isomer) with an amine or amide of formula (IV) in prence of (I); and (iii) the preparation of optically active indolines of formula (V) by cyclization of of o-alkenyl-anilines of formula (VI) (or the corresponding cis-isomer) in prence of (I). R1,R'1 = 1-6C alkyl, aryl, aralkyl, heteroaryl or heteroaralkyl (all optionally substituted); provided that R1 is not R'1-CH2-; or R1 + R'2 together complete a prochiral mono- or bicyclic cycloaliphatic system; R2 = optionally substituted aryl or acyl; R3 = H or optionally substituted acyl alkanesulfonyl or arenesulfonyl; R4 = H

or optionally substituted 1-4C alkyl; R5 = as R2 or R3; R6-R9 = H or 1-6C alkyl or 1-6C alkoxy (both optionally substituted).
