The conformation of alpha -substituted cyclohexanones. Group VIA substituents.
The positions of the conformational equil. of I (R = PhO, PhS, PhSO, PhSO2, PhSe) were detd. by 1H NMR in CCl4, CDCl3, (CD3)2CO, and MeCN, and by calcns. of Delta G0 for the systems. I (R = PhS, PhSO2, PhSe) have preferred conformations with R axial; I (R = PhO, PhSO) have R equatorial.
