Mass spectrometry of π-complexes of transition metals. Communication 32. Derivatives of π-cyclopentadienyl-π-(3)-1,2-dicarbollyliron(III)

Conclusions The basic paths have been established in the fragmentation of derivatives of -cyclopentadienyl--(3)-1,2-dicarbollyliron(III) under electron impact: cleavage of the carbollyl-Fe bond, deep dehydrogenation, dehydration, and dehydrohalogenation. The carbollyl complexes are less stable to electron impact thatn are the ferrocene derivatives. In the molecular ions, the Cp-Fe bond is stronger than the carbollyl-Fe bond.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 10, pp. 2246–2251, October, 1984.
