Abstract
Arenesulphonamides react with tetramethylphosphorodiamidous chloride, NN′-dimethyl-NN′-diphenylphosphorodiamidous chloride, and dimethylphosphoramidous dichloride, to give 1,3-bisarylsulphonyl-1,3,2,4-diazadiphosphetidines in high yields. The dimethyldiphenylphosphorodiamidous chloride also reacts with aniline in the presence of pyridine to give a diphenyldiazadiphosphetidine. but reacts with benzamide to give an N-benzoyltriaminophosphine. Some spectroscopic and chemical properties of the bisarylsulphonyldiazadiphosphetidines are described.Keywords
