Probing the Redox Reactivity of Alkyl Bound Astatine: A Study on the Formation and Cleavage of a Stable At–C Bond Open
The formation of a stable alkyl At-C bond occurs during the shipment of 211At on a 3-octanone-impregnated column and the reactivity of 211At stripped from columns has been studied. The 211At could not be recovered from the 3-octanone organ…

Complexation of Astatine(III) with Ketones: Roles of NO<sub>3</sub><sup>–</sup>Counterion and Exploration of Possible Binding Modes Open
Ketones have been proven effective in extracting astatine(III) from aqueous solvents. Previous theoretical studies suggested a mechanism where the "sp2" lone pair on the carbonyl oxygen donates electron density into the π system of the AtO…
