The diiron complex [Fe2{m-l1(O):h1(C):h3(C)eC(N(Me)(Xyl))C(H)]C(Me)C(O)OMe}(m-CO)(Cp)2] (2) has been obtained from the diiron bridging vinyliminium [Fe2{m-h1:h3eC(Me)]C(H)C]N(Me)(Xyl)}(m-CO) (CO)(Cp)2][SO3CF3] (1; Xyl ¼ 2,5-C6H3Me2) upon treatment with NaH in the presence of CH2]C]CMe2, followed by chromatography on alumina with MeOH as eluent. The reaction consists in the incorporation of a methylcarboxylate unit, assembled from CO and MeO, into the bridging vinyliminium ligand. The resulting complex 2 exhibits a C4 fragment bridging the two iron centres through the carbonyl oxygen atom and the allylidene moiety. The X-ray molecular structure of 2 has been determined.

Abstract

The diiron complex [Fe2{m-l1(O):h1(C):h3(C)eC(N(Me)(Xyl))C(H)]C(Me)C(O)OMe}(m-CO)(Cp)2] (2) has been obtained from the diiron bridging vinyliminium [Fe2{m-h1:h3eC(Me)]C(H)C]N(Me)(Xyl)}(m-CO) (CO)(Cp)2][SO3CF3] (1; Xyl ¼ 2,5-C6H3Me2) upon treatment with NaH in the presence of CH2]C]CMe2, followed by chromatography on alumina with MeOH as eluent. The reaction consists in the incorporation of a methylcarboxylate unit, assembled from CO and MeO, into the bridging vinyliminium ligand. The resulting complex 2 exhibits a C4 fragment bridging the two iron centres through the carbonyl oxygen atom and the allylidene moiety. The X-ray molecular structure of 2 has been determined.
