Facile Synthesis and Crystal Stuructures of New Ammonium Sulfonates (CA-DNBS and TEA-TMBS)

The title compounds,C_(12)H_(10)N_3O_7SCl(I) and C15H27NO3S(n),crystallize in the monoclinic system,space group P2_(1/c) with a=7.3995(1),b=27.8489(6),c=9.8246(2) A,β= 131.349(1)°,V=1519.82(5) A~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) A,V= 3324.67(12) A~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.
