New entry to pentamethylcyclopentadienyl iron chemistry and the methylene complexes [(η5-C5Me5)Fe(CO)(L)(CH2)]+(L = CO or PPh3)

Véronique Guerchais  and  Didier Astruc 

Abstract

Na[(η5-C5Me5)Fe(CO)2](1), a precursor of (η5C5Me5)Fe(CO)2(CH2OMe)(2), is conveniently obtained by Na-Hg reduction of [(η5-C5Me5)Fe(CO)2]2 overnight (20 °C), complex (2) yielding [(η5-C5Me5)Fe(CO)2(CH2PPh3)]BF4(3) upon acid treatment in the presence of PPh3 and converting styrene quantitatively into phenylcyclopropane upon reaction with Me3SiOSO2CF3 giving (η5-C5Me5)Fe(CO)2(OSO2CF3)(4); photolysis of (2)+ PPh3 produces (η5-C5Me5)Fe(CO)-(PPh3)(CH2OMe)(5) which upon acid treatment affords the methylene complex [(η5-C5Me5)Fe(CO)(PPh3)(CH2)]+(6).

    Reproduced material should be attributed as follows:

    • For reproduction of material from NJC:
      Reproduced from Ref. XX with permission from the Centre National de la Recherche Scientifique (CNRS) and The Royal Society of Chemistry.
    • For reproduction of material from PCCP:
      Reproduced from Ref. XX with permission from the PCCP Owner Societies.
    • For reproduction of material from PPS:
      Reproduced from Ref. XX with permission from the European Society for Photobiology, the European Photochemistry Association, and The Royal Society of Chemistry.
    • For reproduction of material from all other RSC journals and books:
      Reproduced from Ref. XX with permission from The Royal Society of Chemistry.

    If the material has been adapted instead of reproduced from the original RSC publication "Reproduced from" can be substituted with "Adapted from".

    In all cases the Ref. XX is the XXth reference in the list of references.

    If you are the author of this article you do not need to formally request permission to reproduce figures, diagrams etc. contained in this article in third party publications or in a thesis or dissertation provided that the correct acknowledgement is given with the reproduced material.
