Abstract
The imido derivates of 2-trifluoroacetylphenol, 1 (R1=H, Me, iPr) react with the isocyanatophosphites (R2O)2PNCO, 2 (R2[dbnd]Et, R2-R2[dbnd]CMe2-CMe2) to yield the bicyclic compounds 3, wheras in case of 1 (R1[dbnd](CH2)2NMe2) the λ3σ3P compounds 4 are found. The phosphorus(III) chlorides R3PC12 (R3[dbnd]Ph, OEt) and 1 (R1[dbnd]H, Me) give rise to furnish the tricyclic phosphoranes 5. However with 1 (R1[dbnd]iPr) phosphite 6 is obtained, which adds hexafluoracetone to give the 1,3,2λ5σ5-dioxaphospholane 7. 2-(Trifluoracetoxy)pyridine 8. reacts with Tris(trimethylsily1)phosphite to yield the bis(phosph0nate) 10. Some molecular structures are discussed on the basis of x-ray diffraction results.
