Chiral, secondary amines of the formula (I) or (II), where R01, R02 and R03 are each, independently of one another, C1-C4-alkyl, R04 is C1-C4-alkyl, C1-C4-alkoxymethyl or C1-C4-alkoxyethyl, and * indicates predominantly one configurational isomer, can be obtained by hydrogenation of corresponding ketimines in the presence of iridium complexes with chiral ferrocene tetraphosphines in which a secondary phosphine group and 1-secondary phosphinalk-1-yl are bound to each cyclopentadienyl ring in ortho positions.
手性的、二级胺的化学式(I)或(II),其中R01、R02和R03分别独立地是C1-C4-烷基,R04是C1-C4-烷基、C1-C4-烷氧甲基或C1-C4-烷氧乙基,*表示主要是一个构型异构体,可以通过在手性二茂铁四膦的铱配合物存在下,氢化相应的酮亚胺来获得,其中二级膦基团和1-二级膦基烷基与环戊二烯基环的每个邻位结合。
