Anionic Bismuth(III) chloride cluster with diselenide countercations: Application in C-S cross coupling reactions

Publication date: Available online 28 January 2019Source: Journal of Organometallic ChemistryAuthor(s): Ganesan Prabusankar, Mannem Adinarayana, Muthukumaran NirmalaAbstractThe first weakly coordinating anion (WCA) with reactive p-block cation (rPBC) type of [(Bi4Cl16)4-{(LSeSeL)2+}2], L = 1,3-bis(2-benzhydryl-4,6-dimethylphenyl)-1H-imidazole-2(3H), ion pair is reported. The tetranuclear anionic bismuth(III) cluster shows a new type of ladder structure with two different types of Bi(III) coordination modes. In the solid state structure, the tetranuclear bismuth(III) cluster is sandwiched by two diselenide cations through hydrogen bonding interactions. Besides, this ion pair has been efficaciously employed as catalyst in C-S cross-coupling reactions under optimized reaction condition. This ion pair depicted a wide range of substrate scope with different thiols and aryl halides.Graphical abstractThe diselenide trapped tetranuclear anionic bismuth(III) chloride cluster for C-S cross-coupling reaction is reported.
