摘要:
[(MeCp)VCl2(PEt3)(2)] (1) and [(MeCp)(2)VCl] (4) (MeCp = eta(5)-C5H4CH3)have been obtained from the reaction between VCl3 and NaMeCp in THF in the presence (1) and absence (4), respectively, of PEt3. The reaction of VCl3 and NaMeCp in the presence of CNt-Bu yielded (impure) [(MeCp)VCl2(CNt-Bu)(2)] (3) and, as a by-product, [(MeCp)(2)V(CNt-Bu)(2)][VCl4(THF)(2)] (2). The crystal and molecular structures of 1, 2 and 4 have been determined. (C) 1999 Elsevier Science S.A. All rights reserved.
