Title:
ORGANOMETALLIC COMPLEXES, CATALYSTS CONTAINING THE SAME, AND PROCESS FOR PREPARATION OF CARBOXYLIC ESTERS
Document Type and Number:
WIPO Patent Application WO/2003/010136
Kind Code:
A1
Abstract:
Organometallic complexes characterized by being represented by the general formula (1), which can be advantageously used in the systems of synthesis of carboxylic esters from aldehydes, e.g., Tishchenko’s reaction: (1) wherein M is a metal atom&semi R is optionally branched C1−8 alkyl or an aromatic or aralkyl group which may be substituted&semi L is an organic group which has one or more aromatic rings and can form a ring composed of five to seven members inclusive of X, Y, and M&semi and X and Y are each independently −O−, −NR1−, −N(SO2R2)−, or the like (with proviso that the cases wherein X and Y are the same are excepted), R1 being optionally branched C1−8 alkyl which may be halogenated and R2 being optionally branched C1−10 alkyl which may be halogenated.
