Comparing Fragmentation Trees from Electron Impact Mass Spectra with Annotated Fragmentation Pathways [PDF]

open access: yes, 2012
Electron impact ionization (EI) is the most common form of ionization for GC-MS analysis of small molecules. This ionization method results in a mass spectrum not necessarily containing the molecular ion peak.

Passerini Reactions on Biocatalytically Derived Chiral Azetidines

open access: yesMolecules, 2016
The purpose of this study was to explore a series of Passerini reactions on a biocatalytically derived enantiopure azetidine-2-carboxyaldehyde in order to obtain, in a diastereoselective manner, polyfunctionalised derivatives having the potential to be ...

N_2 Functionalization at Iron Metallaboratranes [PDF]

open access: yes, 2011
The reactivity of the anionic dinitrogen complex [(TPB)Fe(N_2)]^− (TPB = tris[2-(diisopropylphosphino)phenyl]borane) toward silicon electrophiles has been examined. [(TPB)Fe(N_2)]^− reacts with trimethylsilyl chloride to yield the silyldiazenido complex (

The spectroscopic parameters of sodium cyanide, NaCN (X 1A'), revisited

open access: yes, 2019
The study of the rotational spectrum of NaCN (X $^1$A') has recently been extended in frequency and in quantum numbers. Difficulties have been encountered in fitting the transition frequencies within experimental uncertainties.
