The reaction of Cp*HfCl3 with (1,2,3-Me3allyl)MgBr or (1,1,2-Me3allyl)MgBr and excess MgBr2 yields Cp*(1,2,3-Me3allyl)HfBr2 and Cp*(1,1,2-Me3allyl)HfBr2. X-ray crystallography of these compounds shows a bent-metallocene-type geometry, with steric con

The reaction of CpHfCl 3 •2THF with 2 equiv of (1,2,3-Me 3 allyl)MgBr or (1,1,2-Me 3 allyl)MgBr yields Cp(1,2,3-Me 3 allyl)(1,2-Me 2 butadiene)Hf (3) or Cp(1,1,2-Me 3 allyl)(2,3-Me 2 butadiene)Hf (4). X-ray crystallography of 3 shows that both the
