文摘

The reactions of hexachlorocyclotriphosphazene, N₃P₃Cl₆ (1), with 1,6-diaminohexane (2a) and 1,8-diaminooctane (2b), having long carbon chains, in acetonitrile have been investigated. The reactions gave three different types of products, whose structures have been characterized by elemental analysis, mass spectrometry, ¹H and ³¹P NMR spectroscopy, viz. the triple-bridged compounds N₃P₃Cl₃[NH(CH₂)_nNH]₃N₃P₃Cl₃ [n = 6 (a series); n = 8 (b series)] (3a, 3b), the mono-ansa compounds N₃P₃Cl₄[NH(CH₂)_nNH] (4a, 4b) and the double-bridged compounds N₃P₃Cl₄[NH(CH₂)_nNH]₂N₃P₃Cl₄, (5a, 5b). X-ray crystallographic studies confirmed the structures of the two ansa compounds (4a, 4b) and the meso-anti double-bridged compounds (5a, 5b). The results of both reactions were compared with previous work on the reaction of compound 1 with the same diamines (2a, 2b).
