Angew.Chem.Int.Ed.2011,50,1354～1358金属苯化学是当前金属有机化学的研究热点之一.然而,金属苯的类似物金属杂1,2,4-环己三烯,即“异金属苯”仍很少.此前仅有一例见诸报道.厦门大学化学系夏海平等以锇亚乙烯化合物1为原料,通过简便的室温[3+3]关环法高产率地合成出“异锇苯”.与首例“异金属苯”不同的是:这些“异锇苯”的金属中心具有18e稳定结构,此外, Angew.Chem.Int.Ed.2011, 50,1354 ~ 1358 Metal Benzene Chemistry is one of the hot topics in the field of metalorganic chemistry, however, the metal phenanthrene, Heterocyclic 1,2,4-Cyclohexatriene Only one case reported before .Xia Haiping, Department of Chemistry, Xiamen University with osmium vinylene compound 1 as raw material, by simple room temperature [3 +3] closed ring synthesis method with high yield Unlike the first case of “meta-benzene”, these “meta-osmium” metal centers have a 18e stable structure. In addition,
