## Abstract Intensely coloured, extremely moisture sensitive complexes [VOCl~3~(L)] (L = pyridine, quinoline, Ph~3~PO, Ph~3~AsO, pyridine __N__βoxide), [VOCl~3~(L)~2~] (L = pyridine, Me~3~PO, pyridine __N__βoxide), [VOCl~3~(LβL)] [LβL = 2,2β²βbipyridyl, 1,10βphenanthroline, Ph~2~P(O)CH~2~P(O)Ph~2~,
The reaction of 1,2-diamines la-c with Ph3PBr2 in the presence of triethylamine gives rise to the corresponding diphosphonium salts 2a-c in good yields. Treatment of these salts with NaH at room temperature in CH,Cl, affords the diiminophosphoranes 3a-c in near quantitative yields. Derivatives 3a,b
