DOI: 10.1021/jasms.2c00306
Abstract: Free radical-initiated peptide sequencing (FRIPS) is a tandem mass spectrometry technique that generates sequence informative ions via collisionally initiated radical chemistry. Collision activation homolytically cleaves an installed radical precursor and initiates radical formation, extensive hydrogen… read more here.

DOI: 10.1039/c7ra13481a
Abstract: The hydroauration of functionalised 1-alkenes by the gold(III) hydride (C^NOMe^C)AuH is initiated by organic radicals and proceeds via (C^N^C)Au(II) radical intermediates following a bimolecular outer-sphere mechanism. The outcome of these reactions is determined by the… read more here.
