Abstract
A series of alkoxycyclodiphosph(III)azanes, XP(NBut)2PY [X = Y = OMe (two isomers); X = Y = OEt (two isomers); X = Y = OCH2CF3 (one isomer); X = Y = OBut (one isomer); X = Cl, Y = OMe (one isomer)] has been prepared from the reactions of CIP(NBut)2PCl with alcohols in the presence of triethylamine. The product of reaction with ButOH is easily converted into (ButO)P(NBut)2P(O)H. Analogous reactions with ethane-1,2- and propane-1,3-diols give the cage compounds P(NBut)2[O(CH2)nO]P (n= 2 or 3) and polymeric materials. Geometrical isomers of (MeO)P(NBut)2P(OMe) showed a different degree of reactivity towards methyl iodide, elemental sulphur, or selenium. Isomeric forms of the sulphides and selenides, (MeO)P(NBut)2P(X)(OMe) (X = S or Se), (MeO)(X)P(NBut)2P(X)(OMe) (X = S or Se), and of methyl iodide adducts have been obtained. Aspects of the 1H, 13C, and 31P n.m.r. and i.r. spectra of cyclodiphosph(III)azanes are discussed.
