P-H,P-OR-substituted phosphane complexes 3ae have been
synthesized by two methods: (1) the thermal reaction of 2H-azaphosphirene complex 1 with
methanol, n-butanol, or ethylene glycol monomethyl ether (3b,c,e) or (2) the reaction of P-
chlorophosphane complex 2 with appropriate sodium phenolate salts (3a,d). All the complexes 3ae
were obtained in good yields and fully characterized by NMR, IR, MS, and elemental analysis.
Furthermore, the structures of 3a, 3d and 3e were confirmed unambiguously by X-ray analysis. The
deprotonation of complexes 3ae by using lithium diisopropylamide in the presence of 12-crown-4
led to phosphinidenoid complexes 4ae, which exhibit downfield 31P resonances and small
tungstenphosphorus coupling constants. Studies on the reactivity of complexes 4ac,e revealed a
phosphanido-type reactivity, and only for complex 4d, a thermally labile complex, was evidence
found for a phosphinidene-type reactivity.
