英文摘要 | Trichloromethanesulfenyl acetate, CCl3SOC(O)CH3, belongs to the family of sulfenic esters. This molecule has been characterized by vibrational spectroscopy. The conformational and geometrical properties of this species have been determined by IR and Raman spectroscopy, X-ray diffraction, and quantum chemical calculations. Geometry optimizations of the most stable forms were performed with ab initio (HF, MP2) and density functional theory (B3LYP) methods. According to Our data, this compound results in a gauche-syn conformer with C-1 symmetry (gauche orientation around the S-O bond and syn orientation of the C=O double bond with respect to the S-O single bond) for the most stable geometry, and trans-syn conformer with C-s symmetry (trans orientation around the S-O bond and syn orientation of the C=O double bond with respect to the S-O single bond) for the second stable conformer (1.1 and 0.53 kcal/mol higher in energy than the most stable C-1 form according to the matrix FTIR spectroscopy and MP2/6-31G* level of the theory, respectively). The crystalline solid (monoclinic, P2(1)/n, a = 8.0152(17) angstrom, b = 5.7922(13) angstrom, c = 17.429(4) A, gamma = 90 degrees, 100.34](3)degrees) consists exclusively of the main form. The geometrical parameters (X-ray diffraction) are d(C-Cl) = 1.767(19) angstrom. DC-S = 1.797(2) angstrom, d(S-O) = 1.663(14) angstrom, d(C=O) = 1.189(2) angstrom, d(O-C) = 1.389(3) angstrom, d(C-C) = 1.483(3) angstrom, angles Cl-C-Cl = 1 10.3(11)degrees, Cl-C-S = 111.8(12)degrees, C-S-O = 97.4(8)degrees, S-O-C = 116.7(11)degrees, O-C=O = 122.8(19)degrees, O=C-C = 127.1(2)degrees, and the main torsion angles are delta(CSOC) = 105.9(15)degrees and delta(SOC(O)) = 7.6(3)degrees. The geometrical data calculated with B3LYP/631G++(3df,3pd), 133LYP/6-311G++(3df,3pd), B3LYP/aug-cc-pVTZ, and MP2/6-31G* are in good agreement with diffraction data. |
