The interaction of N,N,N′,N′-tetramethylphosphoric triamide with chloral: Phosphorus-nitrogen fission products and the X-ray crystal structure of N,N,N′,N′-tetramethyl-n″-(2,2,2-trichloro-1- dimethylaminoethyl)phosphoric triamide

The interaction of N,N,N′,N′-tetramethylphosphoric triamide with chloral gives dimethylformamide, chloroform, and a complex mixture of phosphorus-containing products, amongst which N,N,N′,N′-tetramethyl-N″-(2,2,2-trichloro-1- dimethylaminoethyl)phosphoric triamide was characterized by single crystal X-ray diffraction. Dimethylamino(imino)oxophosphorane is postulated as a tricoordinate phosphorus (V) by-product, which undergoes oligomerization or reaction with other components of the reaction system.
