Although BH<sub>3</sub> simply coordinates the endocyclic P of (phospholidino)phosphaketene <b>1<sup>Dipp</sup></b> , the bulkier B(C<sub>6</sub>F<sub>5</sub>)<sub>3</sub> gives rise to a zwitterionic diphosphirenium, which is a novel type of 2π-electron aromatic system as shown by the calculated NICS values. While the reaction of <b>1<sup>Dipp</sup></b> with Na[PCO(dioxane) <sub><i>x</i></sub> ] is unselective, the same reaction with the sterically bulky (phospholidino)phosphaketene <b>1<sup>Ar ...[more]
