Synthesis and Structure of [eta]1-Gallacyclopentadienyl Complexes

The first [eta]1-gallacyclopentadienyl complex 1 was synthesized in solution by reacting dichlorogallyliron complex [Cp*(OC)2FeGaCl2] (2, Cp*: [eta]5-C5Me5) with zirconacyclopentadiene [Cp2Zr(C4Me4)] (3, Cp: [eta]5-C5H5). It was isolated as its Lewis base-stabilized form [Cp*(OC)2Fe{GaC4Me4(DMAP)}]...

Zusammenfassung:The first [eta]1-gallacyclopentadienyl complex 1 was synthesized in solution by reacting dichlorogallyliron complex [Cp*(OC)2FeGaCl2] (2, Cp*: [eta]5-C5Me5) with zirconacyclopentadiene [Cp2Zr(C4Me4)] (3, Cp: [eta]5-C5H5). It was isolated as its Lewis base-stabilized form [Cp*(OC)2Fe{GaC4Me4(DMAP)}] (4, DMAP: 4-(dimethylamino)pyridine) in 47% yield. X-ray crystal structure analysis for 4 revealed almost planar gallacyclopentadienyl core with C-C bond-length alternation.
