2-Ethyl-2,3-dihydro-1,2-benzothiazole-1,1,3-trione
In the title mol-ecule, C(9)H(9)NO(3)S, the bond lengths and angles fall within normal ranges. All nine ring atoms almost lie in a common plane (r.m.s. deviation 0.021 Å). In the crystal, symmetry-related mol-ecules are linked via C-H⋯O hydrogen bonds, forming a three-dimensional network.

In the title compound, C(8)H(7)NO(3)S, the benzene ring is oriented at a dihedral angle of 69.25 (7)° to the S and O atoms of the sulfonyl group. The heterocyclic ring approximates to an envelope, with the N atom in the flap position. In the crystal, mol-ecules are linked by N-H⋯O(c) (c = carbon-yl) hydrogen bonds, forming C(5) chains along [001]. Two R(2) (2)(10) loops arise from pairs of C-H⋯...

The asymmetric unit of the title compound, C(15)H(10)ClNO(4)S, contains two independent conformers wherein the 2-chloro-phenyl group in one is rotated by approximately 180° compared to the other mol-ecule. This affects the S-N-C-C(=O) and N-C-C(=O)-C torsion angles giving vlaues of -87.0 (2) and 158.7 (2)° in one mol-ecule and -104.3 (2) and -173.4 (2)° in the other. The benzisothia-zole ring s...

The title compound, C20H20O3, contains two fused rings with a quaternary carbon centre connecting p-toluoyl and eth-oxy-carbonyl groups. The dihedral angle between the fused benzene ring and the three-C-atom plane (derived from O=C-C-C=O) is 82.5 (4)°, whereas the dihedral angle between the planes of the benzene rings is 53.4 (2)°. In the crystal, molecules are linked via C-H⋯Oester hydrogen bo...
متن کاملEthyl 3-oxo-2,3-dihydro-1,2-benzothiazole-2-carboxylate
The title compound, C(10)H(9)NO(3)S, was synthesized by the reaction of benzo[d]isothia-zol-3(2H)-one with ethyl carbonochloridate in toluol. The benzisothia-zolone ring system is approximately planar, with a maximum deviation from the mean plane of 0.020 (1) Å for the N atom.
