π-烯丙基碘化铁含氮配合物的合成

SYNTHESIS OF NITROGENOUS COMPLEXES OF η~3-ALLYLIRON IODIDE

π-烯丙基卤化铁含氮配位体的络合结构被认为是铁体系催化丁二烯聚合反应的活性中心,所以合成具有这种结构的模型化合物并研究其催化活性是很有意义的。我们曾合成了π-烯丙基氯化铁三吡啶配合物并研究了它对丁二烯聚合的催化活性,但所得配合物混有近等当量的卤化镁难以分离。Nesmeyanov曾合成π-烯丙基卤化铁三羰基化合物η3-C3H5FeX（CO）3（X=Cl,I）。

In this work usin g ligands exchange reaction between η~3-allylirontricarbonyl iodideand α,α′-dipyridyl or phenanthrolire, two new and catalytically active nitrogenous comp-lexes of η~3 -allyliron halide, η~3 -C_3H_5 FeI(CO) dipy and η~3 -C_3H_5 FeI(CO)phen,were synthesi-zed successfully.Their chemical structures were characterized by elemental analysis, GCand IR.
