Mass spectrometry of organic compounds in the group V elements—II: Branched chain aliphatic derivatives

Abstract: The behaviour of compounds I to XI1 under electron-impact (electron voltages 30 and 12 eV) was investigated. The abundance of the ions characteristic of amines was shown to decrease drastically with an increase of chain branching in alkylphosphines. Comparison of the spectra of VII and X led to the conclusion that the unshared electron pair of phosphorus does not affect the fragmentation. The main peaks in the spectra of phosphines corresponded to hydrocarbon fragments. The origins of the main fragment ions we… Show more

“…In a detailed study of small organic compounds of group V elements carried out by Kostyanovski et al, phosphines were investigated by electron ionization (EI) mass spectrometry. 16,17 The fragmentation behavior of phosphine-based ligands as well as organometallic compounds utilizing electrospray ionization (ESI), which is widely used today, has not yet been studied more extensively. 18−20 However, the information on this might be useful when it comes to investigating reactions or even reaction intermediates for example in synthesis and catalysis by means of mass spectrometry and thus being able to assign the structure of the mass values detected.…”

“…In the field of biological and organic mass spectrometry, tandem mass spectrometry has been an essential tool for the identification of analytes for many years. In addition, numerous fragmentation mechanisms are well investigated and described. Yet, this knowledge is difficult to apply when working with phosphine-based ligands or even organometallic compounds. In a detailed study of small organic compounds of group V elements carried out by Kostyanovski et al, phosphines were investigated by electron ionization (EI) mass spectrometry. , The fragmentation behavior of phosphine-based ligands as well as organometallic compounds utilizing electrospray ionization (ESI), which is widely used today, has not yet been studied more extensively. However, the information on this might be useful when it comes to investigating reactions or even reaction intermediates for example in synthesis and catalysis by means of mass spectrometry and thus being able to assign the structure of the mass values detected . In the following, we report on the fragmentation behavior of selected phosphine-based ligands utilizing electrospray ionization in combination with collision-induced dissociation tandem mass spectrometry (ESI-CID-MS/MS) on a quadrupole/reflectron time-of-flight (QTOF) mass spectrometer.…”
