the crude product 2b with aqueous sodium carbonate solution led to the formation of the dinuclear carbonato-bridged complex [(11-Me-BPI)Pd}2(μ-CO3)] (3) which was characterized by an X-ray structure analysis. Reaction of 11-Br-BPI (1c) with a large excess (6 equiv.) of the acetylenes Me3SiCCH, Ph3SiCCH and PhCCH under Sonogashira conditions gave the alkynylated derivatives 11-(Me3SiCC)-BPI (4a), 11-(Ph3SiCC)-BPI
双(2-吡啶亚氨基)异吲哚衍生物(10-Me)-BPI(1a)、(11-Me)-BPI(1b)、(11-Br)-BPI(1c)、(4-Me)-的反应BPI (1d) 和 4-Me-10-tBuBPI (1e) 与 [PdCl2(PhCN)2] 和三乙胺在苯中得到方形平面钯 (II) 配合物 [PdCl(10-Me)-BPI}] ( 2a), [PdCl(11-Me)-BPI}] (2b), [PdCl(11-Br)-BPI}] (2c), [PdCl(4-MeBPI)] (2d) 和 [PdCl( 4-Me-10-tBuBPI)] (2e),分别。用碳酸钠水溶液萃取粗产物 2b 导致形成双核碳桥络合物 [(11-Me-BPI)Pd}2(μ-CO3)] (3),其特征在于 X-射线结构分析。11-Br-BPI (1c) 与大量过量(6 当量)的乙炔 Me3SiCCH、Ph3SiCCH
