Abstract: The bis-cyclodiphosphazane compound Et2C[CH2OPO(μ-N-t-Bu)2PNH-t- Bu]2 (2) and the tetrakis-cyclodiphosphazane compound C[CH2OP(μ-N-t-Bu)2PNH-t-Bu]4 (3) have been synthesized by treating 2,2-diethyl-1,3-propanediol or pentaerythritol with 2 or 4 equiv. of [ClP(μ-N-t-Bu)2P(HN-t-Bu)] (1), respectively. Compounds 2 and 3 have been characterized by X-ray crystallography and solution state NMR. Oxidative addition of o-chloranil to 2 and 3 yields the novel compounds Et2C[CH2OP(μ-N-t-Bu)2P{(HN-t-Bu) (1,2-O2C6Cl4)}]2 (4) and C[CH2OP([t-N-t-Bu)2P{(HN-t-Bu)(1,2- O2C6Cl4)}]4 (5) having two or four P(III) P(Ill)-N-P(V) centers, respectively. The 31P NMR spectra of compounds 4 and 5 show characteristic doublets in the tri- and penta-coordinated regions. © 2003 Elsevier Science Ltd. All rights reserved.
