| titleOfInvention | Method for preparing esters by ether carbonylation |
| abstract | The invention relates to a method comprising the following method steps: a) an initial feed of an ether having 3 to 30 carbon atoms; b) the addition of a phosphine ligand and a compound containing Pd, or the addition of a compound containing Pd and a phosphine ligand; c ) Feeding CO; d) heating the reaction mixture while the ether is converted; wherein the phosphine ligand is a compound of formula ( I ): Where m and n are each independently 0 or 1; R 1 , R 2 , R 3 , and R 4 are each independently selected from-(C 1 -C 12 ) -alkyl,-(C 3 -C 12 ) -ring Alkyl,-(C 3 -C 12 ) -heterocycloalkyl,-(C 6 -C 20 ) -aryl,-(C 3 -C 20 ) -heteroaryl; R 1 , R 2 , R 3 At least one of R 4 groups is-(C 3 -C 20 ) -heteroaryl group; and if R 1 , R 2 , R 3 , R 4 are-(C 1 -C 12 ) -alkyl ,-(C 3 -C 12 ) -cycloalkyl,-(C 3 -C 12 ) -heterocycloalkyl,-(C 6 -C 20 ) -aryl, or-(C 3 -C 20 )- Heteroaryl, each of them may be independently substituted with one or more substituents selected from:-(C 1 -C 12 ) -alkyl,-(C 3 -C 12 ) -cycloalkyl,- (C 3 -C 12 ) -heterocycloalkyl, -O- (C 1 -C 12 ) -alkyl, -O- (C 1 -C 12 ) -alkyl- (C 6 -C 20 ) -aryl Group, -O- (C 3 -C 12 ) -cycloalkyl, -S- (C 1 -C 12 ) -alkyl, -S- (C 3 -C 12 ) -cycloalkyl, -COO- ( C 1 -C 12 ) -alkyl, -COO- (C 3 -C 12 ) -cycloalkyl, -CONH- (C 1 -C 12 ) -alkyl, -CONH- (C 3 -C 12 )- Cycloalkyl, -CO- (C 1 -C 12 ) -alkyl, -CO- (C 3 -C 12 ) -cycloalkyl, -N-[(C 1 -C 12 ) -alkyl] 2 , -(C 6 -C 20 ) -aryl,-(C 6 -C 20 ) -aryl- (C 1 -C 12 ) -alkyl,-(C 6 -C 20 ) -aryl-O- (C 1 -C 12 ) -alkyl,-(C 3 -C 20 ) -heteroaryl,-(C 3 -C 20 ) -heteroaryl- (C 1 -C 12 ) -alkyl,-(C 3 -C 20 ) -heteroaryl-O- (C 1 -C 12 ) -alkyl, -COOH,- SO 3 H, —NH 2 , halogen; and no alcohol was added to the reaction mixture. |
