A new class of electrophilic phosphoniumcations (EPCs) containing a –CF3 group attached to the phosphorus(V) center is readily accessible in high yields, via a scalable process. These species are stable to air, water, alcohol and strong Brønsted acid, even at raised temperatures. Thus, P–CF3 EPCs are more robust than previously reported EPCs containing P–X moieties (X = F, Cl, OR), and despite their
