 Title    und die Röntgenstrukturanalyse eines phosphorhaltigen achtgliedrigen SN-Ringes Synthesis of Four-and Eight-Membered Heterocycles Containing Sulfur, Nitrogen and Phosphorus and the X-ray Structure of a Phosphorus-Containing Eight-Membered SN-Ring  
 Abstract    Eight-membered rings of the composition [S02(NR)2PR']2 3a-d with R = CH3, C2H5, and R' = CH3, CßHs, were prepared from substituted sulfamides and dichlorophosphanes in the presence of a tertiary amine. These molecules were characterized on the basis of X H and 31 P NMR investigations and of mass spectra. 3 a reacts with phosphorus penta-chloride to yield the spirocyclic derivative 4 with the phosphorus atom in the center of two four-membered rings. Methyliodide reacts with 3 a and 3 b under opening of the eight-membered ring and formation of phosphonium salts. The structure of 3 b is discussed in detail. 3b crystallizes in the orthorhombic space group Pna2i with a = 12.60(0), b = 13.27(1), c — 12.62(4) A.
