In this Article, we outline the synthesis of B(C6F5)(3)-coordinated mono-, di-, and trivanadocene phosphorus oxide complexes, Cp2VOP(OB(C6F5)(3))Ph-2 (2), (Cp2VO)(2)P-(OB(C6F5)(3))Ph (3), and (Cp2VO)(3)P(OB(C6F5)(3)) (4), respectively (Cp =eta(5)-cyclopentadienyl). The complexes were synthesized from the known reagents, Cp2VF and Ph2P(O)-OSiMe3 (for 2) or PhP(O)(OSiMe3)(2) (for 3) or (Me3SiO)(3)PO (for 4), via Me3SiF elimination and in the presence of B(C6F5)(3). The multimetallic complexes (3 and 4) could not be synthesized without the capping B(C6F5)(3) Lewis acid, whereas the uncapped version of 2, Cp2VOP(O)Ph-2 (1), has previously been reported by us. Spectroscopic and crystallographic analyses of 2-4 support an increasingly Lewis basic P=O bond upon substitution of -Ph for -OVCp2 fragments (2-4). The increased metal nuclearity also results in increasingly reducing complexes as evidenced by cyclic voltammetry (CV). Magnetic measurements (SQUID) further revealed high-spin complexes with negligible magnetic exchange between V centers. Chemical oxidation of 2 with 0.5 equiv of [Ag][B(C6F5)(4)] resulted in a ligand rearrangement reaction producing the V-IV product, Cp2V(OP(OB(C6F5)(3))Ph-2)(2) (7). In contrast, the oxidation of 4 with the trityl salt, [Ph3C][B(C6F5)(4)], resulted in the isolation of a mixed-valent V-III/V-IV dimetallic species, (Cp2VO2P(OB(C6F5)(3))OVCp2 (9). Both oxidations likely produce the [Cp2V][B(C6F5)(4)] byproduct and evidence for its formation is presented. The synthesis and characterization of the mono- and dimetallic species, Cp2VOP(OBPh3)Ph-2 (8) and (Cp2VO)(2)P(OB(C6F5)(3))OSiMe3 (5), is also reported.
