Abstract

An efficient noble methodology, to synthesise a series of novel dibenzimidazole based selone compounds with high yield has been demonstrated here by using NaH route at room temperature. On the basis of experimental data here a method has been adopted for the evaluation of a series of selone compounds by which σ-donor and π-acceptor components of NHC moieties has been investigated. Moreover, a mild, quantitative, regioselective O-acylative cleavage of cyclic ethers was established by in situ generation of bidentate selones supported bismuth(III) catalysts. In particular, with increasing σ-donation property as well as increasing chelation capability of selone ligands towards bismuth(III) activity of catalyst towards O-acylative cleavage of 2-methyl tetrahydrofuran also increases.
