o-[(Phenyl/p-methoxyphenyl)carbamoyl]benzene sulfonamides were synthesized in a straightforward manner utilizing directly saccharin and aniline/p-anisidine as starting material and their crystal structures have been determined. (C13H12N2O3S): Mr = 276.31, monoclinic, P21/c, a = 10.277(6), b = 7.501(2), c = 16.261(10) Å, β = 96.37(2)°, V = 1,245.8(11) Å3, Z = 4. (C14 H14 N2 O4 S): Mr = 306.33, monoclinic, P21/c, a = 10.381(5), b = 7.861(2), c = 16.837(9) Å, β = 93.43(2)°, V = 1,371.5(10) Å3, Z = 4. In both structures the phenyl rings are inclined at 47.09(7) and 39.88(5)° with respect to each other and the structures are characterized by extensive inter and intramolecular hydrogen bonds. The synthesis and crystal structures of two novel [(aryl)carbamoyl]benzene sulfonamide derivatives have been presented.
以糖精和苯胺/对甲氧基苯胺为起始原料,直接合成了邻[(苯基/对甲氧基苯基)氨基甲酰基]苯磺酰胺类化合物,并测定了它们的晶体结构。(C13H12N2O3S):Mr = 276.31,单斜,P21/c,a = 10.277(6),b = 7.501(2),c = 16.261(10) Å, β = 96.37(2)°, V = 1,245.8(11) Å3, Z = 4. (C14 H14 N2 O4 S):Mr = 306.33,单斜,P21/c,a = 10.381(5),b = 7.861(2),c = 16.837(9) Å,β = 93.43(2)°,V = 1,371.5(10) Å3,Z = 4。在这两种结构中,苯基环的相互倾斜度分别为 47.09(7) 和 39.88(5)°,结构的特点是具有广泛的分子间和分子内氢键。介绍了两种新型[(芳基)氨基甲酰基]苯磺酰胺衍生物的合成和晶体结构。
