Reduction of mer-Cl3W(ODipp)(3) with Na/Hg in the presence of P-4 in toluene afforded the orange complex ((3)-P-3)W(ODipp)(3) (31P = -156 ppm, 10% isolated yield). Unlike the valence-isoelectronic anion [((3)-P-3)Nb(ODipp)(3)](-), treatment with AsCl3 of the neutral ((3)-P-3)W(ODipp)(3) did not transfer the cyclo-P-3 ligand to generate AsP3. Instead, this complex underwent aryloxide ligand transfer to form the red complex ((3)-P-3)W(Cl)(ODipp)(2)(THF) (31P = -143 ppm, 32% isolated yield).
