- W319559384 abstract "The Yanovskii sigma complexes of 2,4-dinitrophenyl sulfone and 2,4-dinitro-, 2,4,4'-trinitro-, and 2,2',4,4'-tetranitrodiphenylsulfones were obtained and isolated in the crystalline form. It was established by PMR, IR, and electronic spectroscopy that they are all products from addition of the acetone residue to the fifth carbon atom of the dinitro-substituted ring; in contrast to polynitrodiphenyl sulfides, the isomeric adducts at the C/sup 3/ atom are not formed. Compared with the analogous complexes of sulfides, the synthesized products possess enhanced thermodynamic stability in an acetone-methanol medium. In DMSO they are rapidly decomposed by traces of water to dinitrophenolate and the corresponding arenesulfinic acids. The decomposition of the methyl dinitrophenyl sulfone complex takes place with preferential substitution of the para-nitro group and the formation of methyl 2-nitro-4-hydroxyphenyl sulfone." @default.
