Synthesis and Structures of (Dialkylamino)ethylcyclopentadienyl Derivatives of Zinc
摘要:
Lithium salts of (dialkylamino)ethylcyclopentadienyl react with either ZnCl2 or Zn(OAc)(2) to afford dimeric derivatives containing bridging chlorides or acetates, respectively. X-ray structural determinations of three such derivatives show that the cyclopentadienyl ligands are bound to the zinc centers in an eta (1) fashion and via their amine groups, thereby leading to a stable six-membered metallacycle.
