Metallocene Coordination to Neutral Alkaline Earth Metal Complexes.
The geometrically constrained, Lewis acidic magnesium diamide complex, [Mg(EtNONTCHP)] (EtNONTCHP = 4,5-bis(2,4,6-tricyclohexylanilido)-2,7-diethyl-9,9-dimethyl-xanthene), forms complexes with a series of metallocenes, [Mg(EtNONTCHP)(η2-Cp2M)] (M = Mn, Fe, Co, or Ni), in which one cyclopentadienyl ring of the metallocene is η2-coordinated to the magnesium center. Treating the heavier group 2 metal amide complexes, [M(EtNONTCHP){N(H)(SiMe3)2}] (M = Ca, Sr or Ba) with ferrocene yields complexes [M(EtNONTCHP)(η5-Cp2Fe)] in which one cyclopentadienyl ring of ferrocene is η5-coordinated to the group 2 metal center. Computational studies on the metallocene complexes reveal that the metallocene-group 2 metal interactions are largely electrostatic in nature.
期刊介绍：
Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics.
Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews.
A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal.
Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
