Aryl selenonium vs. aryl sulfonium counterions in polyoxometalate chemistry: the impact of Se⁺ cationic centers on the photocatalytic reduction of dichromate

Abstract

An aryl selenonium octamolybdate hybrid has been developed for the first time and its photocatalytic properties towards Cr(vi) reduction have been studied and compared with those of an analogous aryl sulfonium octamolybdate hybrid.
