The treatment of acyloin (α-hydroxyketone) O-acylderivatives with tetrabutylammonium fluoride hydrate (TBAF·xH2O)-1-3,propanedithiol system gave the corresponding ketones. Further, it was found that N-methylmorpholine added could prevent the concomitant of unidentified compounds to give the pure products in high yields.
