Addition of selenium(II) bromide to arylalkynylamides-a route to hypervalent T-shaped 10-Se-3 systems
Abstract
A route for the generation of hypervalent T-shaped 10-Se-3 systems is described involving an interaction between in situ prepared selenium(II) bromide and an aryl alkynyl amide derivative. The existence of hypervalent selenium in both the solid and solution states has been supported by X-ray analysis and Se-77 NMR data. (C) 2015 Elsevier Ltd. All rights reserved.
