N-(tert-butyl)-N-((ethoxycarbonothioyl)thio)-2,3,4,5,6-pentafluorobenzamide

As reported by the Alexanian laboratory, this reagent is used for site-selective, intermolecular decarboxylative xanthylation leading to the rapid diversification of carboxylic acids. Once installed, the xanthate group provides direct access to diverse product analogues via several aliphatic C-H transformations, including halogenation, deuteration, vinylation, hydroxylation. Product is best stored in foil-wrapped vials in the freezer when not in use; however, it can be weighed out on the bench without risk of decomposition.
