The configurations and conformations of S-methyl benzothiohydroxamic acid (3) and its S-oxo and S,S-dioxo derivatives (5) and (7) were established by means of a graphical comparison of their dipole moments with those of the corresponding p-nitro compounds.The proton magnetic resonance and infrared spectra of these compounds were also studied.It is concluded that the relative stability of stereoisomers in the series of compounds C 6 H 5 C(NOH)X seems to depend more on the electronic nature of the group X than on its steric requirements.
