资源简介：
Reaction of a transient Li/Cl phosphinidenoid pentacarbonyltungsten
complex 3 (R = C5Me5) with 3-oxetanone,
dihydro-3(2H)-furanone, and dihydro-4H-pyran-4-one led to the novel spirooxaphosphirane complexes 5, 7a,b, and 9a,b having an additional oxygen atom in the ring system, while
δ-valerolactone furnished selectively the P,C-cage complex 10. All complexes have been characterized by heteronuclear
NMR and mass spectrometry and by single-crystal X-ray analysis in
the case of 7a and 9a.
