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.
The invention relates to copper complexes of phosphorus compounds, to a process for their preparation and to their use in catalytic coupling reactions.
