Fragmentation of alkylmercury halides under electron impact and the structure of the C 2H 4HgX + ion (X = Cl, Br, I) in the gas phase

Electron impact mass spectrometry was used to investigate the fragmentation of alkylmercury halides of the RHgX type (X = halogen, R = alkyl). The more common directions of molecular ion dissociation are manifested in the rupture of metalligand bonds, yielding R +, RHg +, XHg + and Hg + ions. The s...

Description
Summary:	Electron impact mass spectrometry was used to investigate the fragmentation of alkylmercury halides of the RHgX type (X = halogen, R = alkyl). The more common directions of molecular ion dissociation are manifested in the rupture of metalligand bonds, yielding R +, RHg +, XHg + and Hg + ions. The spectra of the linear alkyl derivatives show intense peaks for the C 2H 4HgX +ions. The factors which govern the formation of these ions and our quantum chemical calculations (MNDO method) indicate that the most probable structure of C 2H 4HgX + is a halogenmercurinium ion.
