| titleOfInvention | Process for the preparation of 4,4-difluoro-3-oxobutanoic acid esters |
| abstract | The present invention relates to a process for the preparation of a compound of the formula (I), wherein R is C<SUB>1-12</SUB> alkyl, by the contact of a compound of the general formula (II) , wherein R<SUB>1</SUB> and R<SUB>2</SUB> are each, independently, C<SUB>1-12 </SUB>alkyl; or R<SUB>1</SUB> and R<SUB>2</SUB> join together with the nitrogen atom to which they are attached to form an alicyclic amine ring containing 4 to 7 carbon atoms or a morpholine ring, with an acetic acid ester of the general formula (III) CH<SUB>3</SUB>COOR, wherein R is as defined under formula (I), in the presence of a base. |
