Formation of nona(ethyl isocyanide)di-iron from penta(ethyl isocyanide)iron and reaction of penta(t-butyl isocyanide)iron with diphenylacetylene; X-ray crystal structures of nona(ethyl isocyanide)di-iron and tris(t-butyl isocyanide){1,4-bis-(t-butylimino)-2,3-diphenylbuta-1,3-diene}iron
Abstract
U.v. irradiation of [Fe(CNEt)5] in diethyl ether affords [Fe2(CNEt)9], and reaction of diphenylacetylene with [Fe(CNBut)5] gives [Fe(CNBut)3{1–4-η-ButNCC(Ph)C(Ph)CNBut}]; the molecular structures of these complexes are established by single crystal X-ray crystallography.
