Abstract

Our previous spectroscopic (IR, 13 C NMR, UV and UPS), X-ray diffraction and theoretical studies of some β-carbonyl-sulfides and -sulfones XC(O)CH 2 SO n R 2–13 (X = Me, Ar, NR 2 , OR and SR; R = Me, Ar; n = 0 and 2) indicated that these compounds in the gas phase, in solution and in the solid state (for the β-carbonylsulfones) prefer a gauche conformation between the C O and CH 2 –S bonds. For the corresponding β-carbonylsulfoxides XC(O)CH 2 S(O)R ...
