Sulfonylsulfur diimides react with alkali alcoxides to form the salts 1a - g.An X-ray structural analysis of 1f shows the expected geometry with the central threefold coordinated sulfur atom. 1c reacts with elemental chlorine to yield the sodium salt 2, the aza analogue of chlorosulfonic acid.When NaNH2 is used as a nucleophile for the reaction with bis(phenylsulfonyl))sulfur diimide, tris(phenylsulfonylimido)sulfite (3) is formed as the main product.Also the structure of 3 was elucidated by means of an X-ray analysis.Analogous to the SO32--anion, 3 has a central sulfur atom with trigonal pyramidal configuration.The analogous aza compound of the fluorosulfinic acid 4 is formed by the reaction of bis(phenylsulfonyl)sulfur diimide with carefully dried CsF.By the reaction of bis(trimethylsilyl)sulfur diimide with CsF, which contains about 7percent of water, the monomeric cesium salt of sulfonimide is formed.The salts 5a and b were obtained by cation exchange of the cesium salt.Tetraphenylphosphonium methoxide reacts with 5-(trimethylsilyloxy)-1,3λ4,2,4,6-dithiatriazin 1,1-dioxide (6) by elimination of CH3OSi(CH3)3 to yield 7.The anion of 7 contains one carbonyl group.
