摘要

The reaction behavior of 1-hydro-5-carbaphosphatrane(1a)was examined.Treatment of 1a with oxidants such as 3-chloroperoxybenzoic acid(mCPBA)and fBuOCl gave cyclic phosphonate 2 and 1-chloro-5-carba-phosphatrane(4),respectively,via cyclic phosphonite 3,a tautomer of 1a.Compound 4 was readily hydrolyzed to afford 2.Compound 1 a was also sulfurized via 3 by elemental sulfur to afford cyclic thioxophosphonate 5,which was also obtained by reactions in the presence of bases.Treatment of la with bases also proceeded through 3 to give an equilibrium mixture of the corresponding phenoxide anion 10 and the phosphoranide anion 9,which was quenched with Mel to afford a mixture of 11 and 1-methyl-5-carbaphospha-trane(1b).Such reactivities are typical for neutral phosphoranes.Theoretical investigations of these reactivities were also performed.
