Hydride transfer reactions via ion-neutral complex: fragmentation of protonated N-benzylpiperidines and protonated N-benzylpiperazines in mass spectrometry.

An ion-neutral complex (INC)-mediated hydride transfer reaction was observed in the fragmentation of protonated N-benzylpiperidines and protonations in electrospray ionization mass spectrometry and the distribution of the two corresponding product ions was found to depend on the stabilization energy of this INC.

A mechanistic study of fragmentation of deprotonated N,2-diphenyl-acetamides in electrospray ionization tandem mass spectrometry.

The characteristic fragment ions of deprotonated N,2-diphenylacetamides were proposed to be produced via an ion-neutral complex mechanism, which was proved by deuterium-labeling experiments, theoretical calculations and substituent effects.

An experimental and theoretical study on fragmentation of protonated N-(2-pyridinylmethyl)indole in electrospray ionization mass spectrometry.

This study is a case for better understanding the dissociative protonation sites and enriching the knowledge about the role of ion/neutral complexes in ESI-MS, which provides useful information for the structural analysis of organic compounds, especially drug analysis in pharmaceutical chemistry.

Mass Spectrometric Behavior and Molecular Mechanisms of Fermented Deoxyanthocyanidins to Alleviate Ulcerative Colitis Based on Network Pharmacology

Aims Ulcerative colitis (UC) is a type of chronic idiopathic inflammatory bowel disease with a multifactorial pathogenesis and limited treatment options. The aim of the present study is to

Intramolecular transacylation: fragmentation of protonated molecules via ion-neutral complexes in mass spectrometry.

An intramolecular transacylation reaction was observed in the mass spectrometry of molecules containing both benzoyl and carboxymethyl groups on an aromatic heterocyclic core, causing elimination of benzoic acid followed by loss of carbon monoxide.
