“…Reactions result in a formation of selenium-containing five-membered saturated tetrahydroselenophenes 4, and unsaturated dihydroselenophenes 5 and selenophenes 6 [54,56,59,60] (Scheme 1). also included examples of the selenacyles formation due to the use of elemental selenium [40][41][42][43][44][45][46][47][48][49][50][51]. A fairly extensive overview of the use of elemental selenium for the syntheses of different classes of organoselenium compounds, including various heterocycles, were presented by Ma et al in 2021 [52] and Guo et al in 2022 [53].…”

“…In 2019, a small review [39] was published in which some examples of elemental selenium introduction into the molecules of different heterocycles were presented. Quite a number of reviews depicting the syntheses of various selenium-containing compounds also included examples of the selenacyles formation due to the use of elemental selenium [40][41][42][43][44][45][46][47][48][49][50][51].

An overview of the known methods of introducing selenium under the action of elemental selenium into the structures of various saturated, unsaturated, and heteroaromatic selenacycles containing C–Se, N–Se, B–Se, Ge–Se and P–Se bonds is presented. These methods include metal, iodine, bromine or chlorine exchange for selenium and the direct cyclization of 1-(2-bromoaryl)benzimidazoles, polyunsaturated hydrocarbons, acetylenes, propargylic amines, 3-halogenaryl amides, aryl amides, diazo-compounds, 2-aminoacetophenone, and the annulation of ethynyl arenes. Three- and four-component reactions utilizing elemental selenium as one of the components and leading to selenium-containing heterocycles are presented as well.
