The reaction of N-(3-methyl-2-thienylmethylidene)aniline with Fe2(CO)9 under mild conditions in anhydrous benzene gives ironcarbonyl organometallic products 2b, 2c, 5, and an organic product 4c. Complexes 2b and 2c are cyclometalated diironhexacarbonyl isomers, in which the methyl group has migrated from β- to β′- and α′-carbon of the thienyl ring, respectively. Complex 5 is a triironnonacarbonyl cluster
的反应ñ - (3-甲基-2- thienylmethylidene)为Fe苯胺2(CO)9的无水苯温和的条件下使有机金属ironcarbonyl产品2b中,图2c,5,和有机产物4c中。配合物2b和2c是环金属化的二铁六羰基异构体,其中甲基分别从噻吩基环的β-迁移到β'-和α'-碳。络合物5是三铁壬基羰基簇,亚氨基酰基配体封端在三铁平面的顶部,氢原子桥接在两个铁上。有机产品4c是原始席夫碱的氢化产物。对2c和5的单晶进行X射线衍射分析,从而确认其结构。
