摘要：

The reaction of [Cp*(CO)(2)Fe{mu-CH2CH(CH2)(3)}W(CO)(3)Cp]PF6 with NaBPh4 in dry acetone gave [Cp*(CO)(2)Fe{mu-CH2CH(CH2)(3)}W(CO)(3)Cp]BPh4. The bond Fe-C-beta is shorter than that reported for the shorter chain carbocationic complexes. The data suggest that metallacyclopropane character is on the iron side of the molecule both in the solid state and in solution. (C) 2009 Elsevier B.V. All rights reserved.
