PHOSPHORUS-NITROGEN COMPOUNDS. PART 63.¹ THE REACTION OF 6,6-BIS-t-BUTYLAMINO-2,2,4,4-TETRACHLOROCYCLOTRIPHOSPHAZATRIENE WITH DIFUNCTIONAL ALCOHOLS, AMINES, AND AMINOALCOHOLS. THE ³¹P AND ¹H N.M.R. SPECTRA OF THE PRODUCTS

Abstract

The reactions of geminal N₃P³(NHBu^t)₂Cl₄ with difunctional alcohols, amines, and aminoalcohols were investigated and a series of spiro derivatives, N₃P₃(NHBu^t)₂[X(CH₂)_nY]Cl₂ (X = Y = O, NH: n =2,3,4; × = O, Y = NH, n = 2, 3, 4; × = Y = NMe, n = 2, 3; X= NH, Y = NMe; n = 2.3; X= O, Y = NMe, n = 2), N₃P₃(NHBu^t)₂[O(CH₂)_nO]₂Cl₂ (n = 3, 4) as well as a monodentate compound, N₃P₃(NHBu^t)₂[O(CH₂)₃OH]Cl₃, were isolated. The phosphorus-31 and proton n.m.r. spectra of these compounds are discussed. Degeneracies in the phosphorus-31 n.m.r. spectra could be reduced by the use of lanthanide shift reagents and by solvent effects.
