The reactions of the 1,3-dimethyl-1,3-diaza-2-P-substituted-(2-chloroethyl)- or bis(2-chloroethyl)amino-2λ3-phosphorinan-4-ones 1 and 4 with hexafluoroacetone in a molar ratio of 1:2 furnished the spirophosphoranes 2 and 5. In the reaction of 1 with hexafluoroacetone, small amounts of the by-product 3, involving λ4 phosphorus were formed and characterized by 19F and 31P NMR spectroscopy. The 1,3-dimethyl-1
