atoms were assigned by comparing the CD spectra with those of analogous phosphine complexes. The opticallyactivearsines in diethyl ether solution racemize by the addition of hydrochloric acid at room temperature, but their palladium(II) complexes in acetonitrile–ethanol solution containing hydrochloric acid are very optically stable and do not racemize by refluxing for a long time.
手性双齿配体(2-氨基乙基)甲基苯基胂(mpan)和(2-氨基乙基)丁基苯基胂(bpan)是通过制备分别含有(R)-N,N-二甲基-的钯(II)配合物来制备和拆分的。 1-(2-萘基)乙胺和(S)-N,N-二甲基-α-甲基苄胺。光学活性游离胂配体可以很容易地从钯 (II) 配合物和 [MIIX2L] 类型的配合物中释放出来 (MII=Pd, Pt; X=Cl, Br, I; L=R-mpan, S- bpan) 准备好了。记录了这些和相关配合物的吸收和圆二色性 (CD) 光谱,并通过将 CD 光谱与类似膦配合物的 CD 光谱进行比较来指定砷原子的绝对构型。在室温下加入盐酸使乙醚溶液中的旋光胂外消旋,
