Abstract
In this Letter, we disclose the synthesis of novel cyclic tetraselenides starting from mannose which are very unusual and rare and have been synthesised for the first time. The structures are confirmed by X-ray analysis. The reactivity of the reagent tetraethylammonium tetraselenotungstate, (Et4βN)2βWSe4β has been compared with the well-known selenium transfer reagents Li2βSe2β and Na2βSe2β. A tentative reaction mechanism has been proposed
