- Abstract
The salts [(BAC)2PO][BF4] (5) and [(BAC)2PO2][BF4] (4) (BAC=bis(diisopropylamino) cyclopropenylidene), consisting of the PO+ and PO2+ cations, respectively, coordinated to the singlet carbenes, have been prepared. Computational investigations reveal that the electronic structure of the PO+ cation is a hybrid between the charge‐localized and charge‐delocalized resonance forms, resulting in ambiphilic reactivity. Compound 5 reacts as a donor with the transition‐metal complex K2PtCl4 to furnish [[(BAC)2PO]2PtCl2][BF4]2 (6) and KCl. Remarkably, both 5 and 4 have shown to act as electrophiles undergoing reactions with fluoride anion, leading to [OPF2]− and (BAC)PO2F, respectively.
