Borinine-FLP ring expansion: isolation of eight-membered B–P rings bridged by μ 2 chalcogenide and chloronium ions

Year: 2025

Type: article

Abstract: led to the formation of a cationic ring-expanded compound with a bridging B-Cl-B motif. This motif constitutes one of the first examples of a boron-stabilized chloronium ion, as verified using in-depth bonding analysis methods. Mechanistic pathways for the reduction- and halide abstraction-mediated ring expansion reactions are proposed with the aid of density functional theory. Electronic structure computations were performed to determine the best representation of bonding interactions in each compound, suggesting phosophorus(V)-chalcogen double bonding and chalcogen-boron(iii) dative interactions within the heterocycles.
