Abstract
The invention relates to a process for doubly carbonylating allyl alcohols to the corresponding diesters, wherein a linear or branched allyl alcohol is reacted with a linear or branched alkanol (alcohol) with supply of CO and in the presence of a catalytic system composed of a palladium complex and at least one organic phosphorus ligand and in the presence of a hydrogen halide selected from HCl, HBr and HI.
Claims11
Process for doubly carbonylating allyl alcohols to diesters, comprising:
- reacting, in a single step, a linear or branched allyl alcohol with a linear or branched alkanol with supply of CO and in the presence of a catalytic system composed of a palladium complex and at least one organic phosphorus ligand and in the presence of a hydrogen halide selected from HCl, HBr and HI, wherein both the allyl portion and the alcohol portion of the allyl alcohol are reacted with the CO.
