Samantha’s publication on the “ Dynamic Reactivity: Reversible Reaction of a Phosphinine–Borane Adduct With Water and Double Hydrophosphination” is now published in Chemistry – A European Journal. We report on the unprecedented reversible addition of water to a 3,5-bis(SiMe₃)phosphinine→B(C₆F₅)₃ adduct and the subsequent formation of novel 1,2- and 1,4-dihydrophosphinine oxide–borane adducts. Furthermore, the reaction of the dihydrophosphinine oxides with the sterically demanding and weak base tris(tert-butyl)phosphine was investigated. Thereby, we observed a unique double hydrophosphination, yielding a bicyclic diphosphine oxide. This work highlights a new mode of small molecule activation and dynamic structural interconversion by aromatic phosphorus heterocycles.

Congratulations and many thanks to our cooperation partners from Budapest!
