	Title	Preparation and X-Ray Structure of 3,5-Dimethyl-1,4-dichloro-1,2,6- thiadiazine-1 -oxide
	Abstract	The title compound was obtained by the reaction of 3,5-dimethyl-2//-l,2,6-thiadiazine-l,l-dioxide with PCI5 in chloroform. It crystallizes in the monoclinic system, space group P2\/c, a = 7.521(7) A, b = 8.400(4) A, c = 13.908(4) Ä, ß = 100.35(4)°, V = 864.4(8) A3, and Z = 4. The S(VI) atom lies 0.43 A out of the plane of the 7r-delocalized NCCCN unit. The mean S-N bond distance is 1.569(3) A.

	Title	Phosphenium-Komplexe, X X IX [1]
	Abstract	[4+2]-Cycloadditionen von Phospheniumkomplexen des Typs C p (O C)2W = P R 2 (R = Alkyl, A ryl) mit 2,3-Dimethylbutadien Phosphenium Complexes, X X IX [1], [4+2]-Cycloaddition of Phosphenium Complexes of the Type Cp(OC)2W=PR2 (R = Alkyl, Aryl) with 2,3-Dimethylbutadiene The phosphenium complexes Cp(OC)2W=PR2 [R = Ph, o-Tol, Me, t-Bu, (2a -d)] react with 2,3-dimethyl-1,3-butadiene (3) via [4+21-cycloaddition to form the phosphametallacyclohexe nes Cp(OC)2W-PR2-CH2-CMe=CMe-CH2 (4a -d). The structure of 4a has been determined by X-ray diffraction.

	Title	Synthesis of Spirocyclic Aminosilanes with Electron Withdrawing Substituents at Nitrogen
	Abstract	The first synthesis of spirocyclic tetrasulfonamidosilanes is described. According to the X-Ray structure analysis of the most stable tetratosylamidosilane obtained the Silicon is bonded to four Nitrogen atoms in a spirocycle and surrounded by four Oxygen atoms which are located above the planes of the SiN4 tetrahedron.
