摘　　要：〔Ｎ｛Ｐ（Ｃ６Ｈ５）３｝２〕〔ＨＦｅ３（ＣＯ）１１〕与异氰酸苯酯反应，酸化后给出簇合物Ｆｅ６（ＣＯ）１４（μ－ＣＯ）３－（μ－η２－ＯＯＣＮＣ６Ｈ１１）．异氰酸苯酯的Ｃ＝Ｏ双键劈开加氧，以（μ－η２－ＯＯＣＮＣ６Ｈ１１）形式配位于２个铁原子．异氰酸苯酯的苯基加氢还原为环己基．同时表征了产物的ＩＲ、１ＨＮＭＲ和ＭＳ谱．The reaction of N{P(Ph) 3} 2 HFe 3(CO) 11 with phenylisocyanate and succeeding acidification gives cluster Fe 6(CO) 14 ( μ CO) 3( μ η 2 OOCNC 6H 11 ).The ligand (μ η 2 OOCNC 6H 11 ) formed by the cleavage of the double bond (C=O) and the insertion of the oxygen atom of phenylisocyanate bridges two iron atoms of the title cluster.During the reaction,the phenyl group of the phenylisocyanate is reduced to cyclohexyl group by the addition of hydrogen.The title cluster is characterized by IR, 1HNMR and MS spectra.
