dc.description.abstract | Single-crystal X-ray diffraction studies are reported for 3,4-diphenyl-1,2,5-thiadiazoline 1,1-dioxide (I), 3,4-diphenyl-1,2,5-thiadiazolidine 1,1-dioxide(II) and 4-ethoxy-5-methyl-3,4-diphenyl-1,2,5-thiadiazoline 1,1-dioxide (III). Ab initio MO calculations on the electronic structure, conformation and reactivity of these compounds are also reported and compared with the X-ray results. A charge sensitivity analysis is performed on the results applying concepts derived from density functional theory, obtaining several sensitivity coefficients such as the molecular energy, net atomic charges, global and local hardness, global and local softness and Fukui functions. With these results and the analysis of the dipole moment and the total electron density and electrostatic potential maps, several conclusions have been inferred about the preferred sites of chemical reaction of the studied compounds. © 2001 Elsevier Science B.V.
