Abstract
The present invention relates to a process for manufacturing para-eugenol and/or ortho-eugenol, comprising a step (i) of deallylation of at least one compound of formula (I): in which R1 and R2 are different, and are chosen from the group consisting of hydrogen and an allyl group (—CH2—CH═CH2).
Claims11
A process for manufacturing para-eugenol and/or ortho-eugenol, comprising:
- deallylating at least one compound of formula (I) in the presence of a catalyst, a base, and a solvent or a solvent/water mixture to form a deallylated product, wherein the solvent comprises a polar solvent, a protic solvent or a solvent/water mixture, and wherein the deallylating is performed in the presence of a Pd/C or Pt/C catalyst:
- wherein R1 and R2 are different, and are selected from the group consisting of hydrogen and an allyl group —CH2—CH═CH2, and
- obtaining the para-eugenol and/or ortho-eugenol from the deallylated product.
