Abstract: <i style="">r</i><b style="">-</b>2,<i style="">c</i>-6-Diphenylpiperidin-4-ones <b style="">2-6</b> and <i style="">r</i>-2,<i style="">c</i>-6-diphenylpiperidine <b style="">7</b> are treated with DMD and the reaction is found to yield only the corresponding <i style="">N</i>-hydroxy derivatives <b style="">8-13</b>. The preferred conformations of the <i style="">N</i>-hydroxy compounds <b style="">8-13 </b>are analysed using the NMR spectra and semiempirical molecular orbital calculations. The <i style="">N</i>-hydroxy derivatives <b style="">8-13 </b>are<b style=""> </b>found to prefer distorted chair conformations.
