Conformational investigation of ?-methylthio-substituted acetone, cyclohexanone, and caran-4-one
摘要:
Trans-3-methylthiocaran-4-one was synthesized. Its structure was established by x-ray structural analysis. The dipole moment was determined. The molar Kerr constants were measured, and the dipole moments were determined, for alpha-methylthioacetone and alpha-methylthiocyclohexanone. It was found that the low-polar gauche conformer at the C-S bond is realized in all cases for the acstate at the C-C(O) bond in the methylthiocarbonyl fragment.
