thylindole (Hp-iepp) (H denotes a dissociable proton), were synthesized, and the structures of [Pd(tbu-iepp)Cl] (1a), [Pd(tbu-iepp-c)Cl] (1b), [Pd(tbu-miepp)Cl] (3), and [Pd(p-iepp-c)Cl] (4) (tbu-iepp-c and p-iepp-c denote tbu-iepp and p-iepp bound to Pd(II) through a carbon atom, respectively) were determined by X-ray analysis. Complexes 1a prepared in CH(2)Cl(2)/CH(3)CN and 3 prepared in CH(3)CN
包含悬垂吲哚、3-[N-2-吡啶甲基-N-2-羟基-3,5-二(叔丁基)苄氨基]乙基吲哚 (Htbu-iepp) 的新型 2N1O 供体配体的 Pd(II) 配合物, 1-methyl-3-[N-2-pyridylmethyl-N-2-hydroxy-3,5-di(tert-butyl)benzylamino]ethylindole (Htbu-miepp), 3-[N-2-pyridylmethyl-N- 2-羟基-3,5-二(叔丁基)苄氨基]甲基吲哚(Htbu-impp)和3-(N-2-吡啶甲基-N-4-羟基苄氨基)乙基吲哚(Hp-iepp)(H表示可解离的质子),合成 [Pd(tbu-iepp)Cl] (1a)、[Pd(tbu-iepp-c)Cl] (1b)、[Pd(tbu-miepp)Cl] (3) 的结构和 [Pd(p-iepp-c)Cl] (4)(tbu-iepp-c 和 p-iepp-c
