  Organochromium π-complexes—VIII. Reactions of the (η5-Me5C5)Cr-system with 1,3-dienes and alkynes

  摘要：

  Cp*(eta4-1,3-diene)Cr compounds have been prepared either by reacting Cp*(eta3-C3H5)2Cr with a diene or by reducing Cp*Cr(THF)Cl2 with activated-Mg in the presence of the diene. These coordinatively and electronically unsaturated species readily form adducts with CO or P-donor ligands. The reaction of Cp*(eta4-1,3-C4H6)Cr with further butadiene leads to the formation of Cp*(eta3,eta3-octadienediyl)Cr which in tum reacts with a disubstitued alkyne (RC2R) with addition to the 2,7-positions of the octadienediyl chain to give Cp*(eta1,eta2,eta1-R2C10H12)Cr species. The crystal structures of representative compounds have been established by X-ray diffraction.
