Synthesis of mono- and di-cationic phosphorus–zirconium species
Abstract
Synthesis and characterisation of zirconium containing phosphonium salts are reported, including the X-ray molecular structure determination of [{(Pri2)N}2P(Me)(CH2)2C(NBut)Zr(η-C5H5)2OSO2CF3]OSO2CF35a; lability of the zirconium–oxygen covalent bond in 5a allows the preparation of the phosphorus–zirconium dicationic species 6a[{(Pri2)N}2P(Me)(CH2)2C(NBut)Zr(η-C5H5)][(OSO2CF3)]2.
