Notes:
The positive ion mass spectra of the π-pyrrolyl derivatives C4H4NMn(CO)2L (L = (C6H5)3E or CO; E = P, As, or Sb), the π-indenyl derivatives C9H7Mn(CO)2L (L = (C6H5)3E or CO; E = P, As, or Sb) and the π-fluorenyl derivatives C13H9Mn(CO)2L (L = (C6H5)3P or CO) have been investigated. The relative tendencies of ions of the type [QMnE(C6H5)3]+ (Q = π-pyrrolyl, π-indenyl, or π-fluorenyl; E = P, As, or Sb) to fragment by losses of the Q ring system and the (C6H5)3E ligand are compared. Phenyl transfers from phosphorus, arsenic, or antimony to manganese to form relatively high abundances of [C6H5Mn]+ are also observed. Other processes typical of metal carbonyl derivatives (CO losses), aromatic derivatives (C2H2 eliminations) and (C6H5)3E derivatives (phenyl losses, conversion of [(C6H5)3E]+ directly to [C6H5E]+, and formation of [C12H8E]+ 9-heterofluorenyl ions) are observed in these mass spectra and are supported in many cases by the presence of appropriate metastable ions.
