The acceptor properties of some pentafluorophenylphosphorus(V) species
Abstract
The acceptor properties of P(C6F5)nCl5–n(1 ⩽n⩽ 3), [P(C6F5)nCl4–n]+(1 ⩽n⩽ 3), and [P(C6F5)Br3]+ towards Lewis bases, such as the chloride ion and uni- and bi-dentate pyridines, have been investigated. Several new complexes have been isolated, and characterised by elemental analysis and (in some cases)31P n.m.r. and/or i.r. spectroscopy.
