Abstract
The formation of phosphinidenoid complex salts having weakly coordinating cations (WCCs) is reported via treatment of P-functional phosphane complexes with N,N’-di-tert-butyl imidazol-2-ylidene or a P4-t-Bu phosphazene base. The thermal stability of phosphinidenoid complex salts is dependent upon the P–X substituents and the nature of the WCC. The complexes were characterized by multinuclear NMR spectroscopy and confirmed by single-crystal X-ray structure.
