Introducing multiple cationic charges into inorganic or organic compounds dramatically influences their reactivities owing to a marked increase in electrophilicity and electron affinity.[1] In the realm of organic chemistry, the self-activated silyl-assisted poly-onio-substitution (SASAPOS) protocol [2] represents a powerful method for the preparation of spectacular polycationic frameworks, for example, a twentyfold cationic cluster with a porphyrin core.[2a] So far, the SASAPOS protocol has been predominantly applied to halogenated hydrocarbon-based systems. Applications in inorganic chemistry are extremely rare. In a pioneering study, Weiss and Engel showed that di-and tricationic phosphorus (III) compounds I and II may be generated by treating PCl3 with an appropriate ligand (L; for example, 4-dimethylaminopyridine (DMAP)) and Me3SiOTf (Scheme 1).[3] Cations I and II were proposed solely on the basis of spectroscopic and chemical analysis data and represent rare examples of di-or trications of trivalent phosphorus compounds.[3, 4]
