Selenium-containing π-Bond Compounds of Heavier Main-Group Elements

Abstract

This review highlights the unique chemistry of π-bond compounds consisting of both selenium and other heavier main-group element, which exhibit intriguing reactivity and potential applications in catalysis, materials science, and bioinorganic chemistry. While selenium shares similarities with sulfur, its larger atomic size and greater polarizability give Se-containing double bonds distinctive characteristics that often result in higher reactivity. This review will focus on recent advancements of compounds that contain a π-bond containing selenium and other heavier main-group elements as well as unique π-conjugated systems, rather than on well-established compounds such selenoketones and selenoamides.
