Abstract
The title compounds, C12H10N3O7SCl (I) and C15H27NO3S (II), crystallize in the monoclinic system, space group P2(1)/c with a = 7.3995(1), b = 27.8489(6), c = 9.8246(2) angstrom, beta = 131.349(1)degrees, V = 1519.82(5) angstrom(3), Z = 4, F(000) = 768, R-int = 0.033 and S = 1.03 for I, and in the orthorhombic system, space group Pbca with a = 8.6227(1), b = 16.1480(4), c = 23.8774(6) angstrom, V = 3324.67(12) angstrom(3), Z = 8, F(000) = 1312, R-int = 0.024 and S = 1.04 for II. We have devised a convenient procedure for the synthesis of fused organic salts resulting from 1:1 proton-transfer, using an amine and a derivative of benzenesulfonic acid. The synthesized salts have a number of applications ranging from their consumption as eco-friendly solvents and catalysts in organic syntheses, to being used as efficient precursors for the production of sulfa drugs. Structures of compounds 3-chloroanilinium 2,4-dinitrobenzenesulfonate (CA-DNBS) and triethylaminium 2,4,6-trimethylbenzenesulfonate (TEA-TMBS) were determined by single-crystal X-ray diffraction studies and infrared spectroscopy.
