The stabilities of a series of isolated covalent selenium(II) azides such as [2-[1-(3,5-dimethylphenyl)-2-naphthyl]-4,5-dihydro-4,4-dimethyloxazole]selenium azide (2a), [2-(4,4-dimethyl-2-oxazolinyl)phenyl]selenenyl azide (3a), [o-(2,6-diisopropylphenyl-iminomethinyl)phenyl]selenenyl azide (4a), [o-(R)-(methylbenzyliminomethinyl)phenyl]selenenyl azide (5a) and o-formylphenylselenenyl azide (6a)...
Human manganese superoxide dismutase (MnSOD) labeled with 3-fluorotyrosine (Tyf) was complexed with the (15)N-labeled inhibitor azide ([(15)N(3)(-)]). The sample was characterized by solid-state NMR (SSNMR) spectroscopy ((19)F-MAS and (15)N-CPMAS). Employing (19)F-(15)N-REDOR spectroscopy, we determined the distances between the fluorine label in Tyrosine-34 and the three (15)N-nuclei of the az...
The nitrile imine-mediated tetrazole–ene cycloaddition is a widely used class of photoligation. Optimizing the reaction outcome requires detailed knowledge tetrazole photoactivation profile, which can only partially be ascertained from absorption spectroscopy, or otherwise involves laborious monitoring in solution. Photodissociation action spectroscopy (PDAS) combines advantages optical and mas...
