Phosphorus–nitrogen compounds. Part 55. The reactions of 2,2,4,4-tetrachloro-6,6-diphenylcyclotriphosphazatriene with aliphatic difunctional alcohols, amines, and aminoalcohols. Proton and phosphorus-31 nuclear magnetic resonance spectroscopic studies of the products

Abstract

The reactions of geminal N₃P₃Ph₂Cl₄ with aliphatic difunctional alcohols, amines, and aminoalcohols have been investigated. A series of monospiro derivatives, N₃P₃Ph₂[X(CH₂)_nY]Cl₂[X = Y = O or NH, n= 2–4; X = O, Y = NH, n= 2–4; X = Y = NMe, n= 2 or 3; X = NH, Y = NMe, n= 2 or 3; X = O, Y = NMe, n= 2] were obtained and the ³¹P and ¹H n.m.r. spectra investigated. The field and temperature dependences of the ³¹P n.m.r. spectra were used in the study of degenerate spectra. Non-equivalence of methylene protons in the spiro rings is observed in the ¹H n.m.r. spectra of these compounds.
