| titleOfInvention | Process for the preparation of carboxylic acid esters |
| abstract | There is provided a process for preparing a carboxylicnacid ester of formula (3): R 2 COOR 1 (3)n wherein R 1 is an alkyl group which may be substituted, nan alkenyl group which may be substituted, nan alkynyl group which may be substituted, nan aralkyl group which may be substituted, or na heteroarylalkyl group which may be substituted, and R 2 is an alkyl group which may be substituted, nan alkenyl group which may be substituted, nan alkynyl group which may be substituted, nan aryl group which may be substituted, na heteroaryl which may be substituted, nan aralkyl group which may be substituted, or na heteroarylalkyl group which may be substituted, n which process is characterized by the steps ofnreacting a monohydroxy compound of formula (1):n R 1 OH nwherein R 1 is as defined above, with a zirconium compound ofnformula (6):n Zr(OR 8 ) 4 nwherein R 8 is an alkyl group or an aryl group which may bensubstituted and is not the same as R 1 , to prepare a zirconiumncatalyst, and reacting a carboxylic acid of formula (2):n R 2 COOH nwherein R 2 is as defined above, with the monohydroxy compoundnof formula (1) in the presence of the zirconium catalyst. |
