  摘要：

  Cr(PMe3)2Cl2 reacts with active-Mg and butadiene or Mg(butadiene) in a stepwise manner to give initially (eta-4-1,3-C4H6)Cr(PMe3)2Cl which reacts further to (eta-4-1,3-C4H6)2CrPMe3. Related compounds are formed in the presence of PMe2Ph or 2,3-dimethylbutadiene. Cr(PEt3)2Cl2 reacts to give the dimeric species [(eta-4-2,3-dimethylbutadiene)Cr(PEt3)Cl]2, whereas in the presence of the bidentate ligand bis(diisopropylphosphino)ethane, (eta-4-1,3-C4H6)Cr(Pr2(i)PC2H4PPr2(i)) is formed. Related reduction of CrCl2-derivatives in the presence of alkynes leads to the formation of (eta-2-R'C = CR')2Cr(PR3)2 (R' = Me, Ph) and (eta-2-PhC = CPh)3CrPMe3.
