含氮杂原子桥联双环戊二烯基二氯化锆配合物的合成

Synthesis of N-containing 5-ansa-Zirconocene Dichloride Complexes

近年来桥联二茂锆配合物的化学引起了金属有机化学家的兴趣,这是由于与非桥联二茂锆化合物相比,它们在结构上和反应性能上都有独特之处。文献中只报道了含 C、Si、Ge 和 O 的桥联二茂锆配合物的合成。

Two new 5-ansa-zirconocene dichloride complexes 1 and 2,which contain N betero atom in the bridge chain,have been synthesized in good yield [equations (1)～(4)].It appears that the flexibility of the bridge chain has no effect on the formation of the zirco-nocene dichloride complexes.The two compounds are identified by elemental analysis,1~HNMR,MS and IR spectroscopies.(?)1:X=CH_3N (CH_2CH_2→2;2:(?)
