1,3,2-Diazaphosphorinanes. V. Synthesis and properties of 2-alkoxy(aryloxy)-1,3,2-diazaphosphorinanes
The reaction of 1,3-alkylenediamines with ethyl and phenyl tetramethyldiamidophosphites has yielded for the first time 2-ethoxy(phenoxy)-1,3,2-diazaphosphorinanes containing two secondary amido groups in the ring. The reaction of 2-ethoxy-1,3,2-diazaphosphorinane with amides and amidoesters of phosphorus acids has given bis-N,N'-phosphorylated diazaphosphorinanes. From /sup 1/H, /sup 13/C, and /sup 31/P NMR spectral data the structures of these compounds were confirmed and it was concluded that they have the chair conformation and axial orientation of alkoxy groups. Chemical shifts and spin-spin coupling constants of the phosphorus nucleus were determined. The spectral parameters of multispin P-P systems were calculated from the type of second-order spectrum.
