Abstract A series of bridging carbyne butterfly Fe/Se cluster complexes (μ-EtOC)(μ-RSe)Fe2(CO)6 (2–8: R=p-MeC6H4, m-MeC6H4, o-MeC6H4, α-C10H7, p-MeOC6H4, p-BrC6H4, p-ClC6H4) have been synthesized by in situ reaction of the [Et3NH]+ salts of anions [(μ-RSe)(μ-CO)Fe2(CO)6]− (1) with electrophile Et3OBF4 in benzene at room temperature. Products 2–8 are new and have been characterized by elemental analysis
摘要 一系列桥联卡宾蝶 Fe/Se 簇配合物 (μ-EtOC)(μ-RSe)Fe2(CO)6 (2-8: R=p-MeC6H4, m-MeC6H4, o-MeC6H4, α-C10H7, p-MeOC6H4、p-BrC6H4、p-ClC6H4) 已通过 [(μ-RSe)(μ-CO)Fe2(CO)6]- (1) 阴离子盐 [Et3NH]+ 与室温下苯中的亲电子试剂 Et3OBF4。产品 2-8 是新产品,已通过元素分析、IR、1H 和 13C-NMR 光谱以及 X 射线衍射分析进行了表征。1H-和 13C-NMR 光谱表明溶液中的 2-8 由两种异构体 R(a) 和 R(e) 组成,而 X 射线衍射分析表明 2 的单晶 (R=p-MeC6H4)由一种异构体R(a)组成。2是第一个通过阴离子1与Et3OBF4反应合成的结构特征复合物,
