Abstract The palladium catalyzed telomerization of butadiene with glycerol has been efficiently performed with bubbling butadiene at atmospheric pressure leading to high selectivities into monooctadienyl glycerylethers. The catalytic activity is found to be stable for a long period of time, up to 5 days, giving rise to turnover numbers as high as 1000. The reaction has been extended to isosorbide and solketal with always selective production of the monotelomers over long time.
