摘要:
AbstractThe eight‐membered chloro hafnium siloxane complex [Cl2HfOtBu2SiO(THF)2]2 2 has been prepared by the reaction of hafnium tetrachloride and tBu2Si(OSnMe3)2 1. The X‐ray single crystal structure of [Cl2HfOtBu2SiO(THF)2]2 is reported. The reaction of 2 with Me3SnF in a molar ratio of 1:4 leads to the corresponding fluoro complex 3. The reaction of [(C5Me5)HfCl3] with the lithiated silanediol tBu2Si(OLi)2 yields [(C5Me5)ClHfOtBu2SiO]2 4.
