Telomerisation of 1,3-butadiene with glycerol under aqueous biphasic conditions: Influence of the reaction conditions on the products distribution

The palladium-catalyzed telomerisation of butadiene with glycerol has been studied under aqueous biphasic conditions both in the presence of a liquid phase of butadiene and under gaseous atmosphere of butadiene. In this last case, gaseous butadiene was continuously added during the whole reaction time keeping constant its pressure. Most of the products formed have been fully characterized. The influence of various experimental parameters has been checked with the aim to obtain high activities and selectivities either into mono-, di- or tritelomers.

The telomerisation of butadiene with glycerol catalyzed by palladium under aqueous biphasic conditions has been investigated in detail as well as under gaseous atmosphere of butadiene than in the presence of a liquid phase of butadiene. The influence of various experimental parameters such as the nature of the hydrosoluble ligand, the nature of the base and its amount, the amount of butadiene or water, …, has been checked with the aim to obtain high activities and selectivities either into mono-, di- or tritelomers.Figure optionsDownload high-quality image (68 K)Download as PowerPoint slide
