Syntheses of some new methylcyclopentadienylmolybdenum complexes: Characterizations, crystal structures and comparisons with related complexes
摘要:
As part of a long-term study of the substitution reactions of piano-stool type cyclopentadienylmetal carbonyl complexes, several new methylcyclopentadienylmolybdenum compounds have been prepared and characterized by methods including IR spectroscopy, electrospray ionization mass spectrometry and X-ray crystallography. The complexes reported here include [{Cp'Mo(CO)(3)}(2)I]BPh4, cis-Cp'Mo(CO)(2)(PPh3)I and [Cp'Mo(CO)(3)(CH3CN)]BF4 (Cp' = eta(5)-C5H4CH3). In addition to their syntheses, comparisons are made between their IR spectroscopic and X-ray crystal structure data and those of similar complexes. (C) 2009 Elsevier B.V. All rights reserved.
