 Title    N,N',N'-Trimethylethylendiamin-substituierte Phosphor(III)-Verbindungen und deren Oxidation zu Derivaten mit tetra-und pentakoordiniertem Phosphor N,N',N'-Trim ethylethylenediam ine-Substituted Phosphorus(III) Com pounds and their Oxidation to Derivatives with Four-and Five-Coordinated Phosphorus  
 Abstract    A study was made o f the intramolecular donor-acceptor interaction in N ,N',N'-trim ethyl-ethylenediamine-substituted phosphorus com pounds, involving A3-, A4-and A5-phosphorus atom s, as a function o f the nature o f the substituents at phosphorus. The reaction o f N-trim ethylsilyl-N,N',N'-trim ethylethylenediam ine (1) with (Pr'0)2PCl furnished the acyclic, trimethylethylenediamine-substituted phosphorus(III) compound 4. There is no N M R spec­ troscopic evidence for an intramolecular donor-acceptor interaction between the phosphorus atom and the nitrogen atom o f the dim ethylam ino group in 4. The oxidation o f the trivalent phosphorus atom in 4 and in the related com pound 5 by sulfur, selenium, tetrachloro-o-benzoquinone, and hexafluoroacetone led to the corresponding A4P com pounds 6 -9 and to the A5P com pounds 10 and 11. N o intramolecular donor-acceptor interaction could be detected in any o f these products. There was no reaction between 5 and elemental tellurium. The reac­ tion products were characterized by N M R spectroscopy, mass spectrometry, and by elemental analysis.
