Abstract

A process for producing an aromatic compound in high yield and a palladium complex are provided. The palladium complex is represented by formula (D) or formula (D′):In formula (D), X represents a chlorine atom, A represents an alkyl group having 1 to 3 carbon atoms, B represents an alkyl group having 4 to 20 carbon atoms or a cycloalkyl group having 5 to 10 carbon atoms, R4 and R5 each independently represent a hydrogen atom, a fluorine atom, or an alkoxy group having 1 to 20 carbon atoms, and R6, R7 and R8 represent a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms or a heteroaryl group having 4 to 20 carbon atoms.In formula (D′), X, A, B and R4 to R8 are the same as defined above.

First claim

The invention claimed is:

1. A palladium complex represented by the formula (D) or the formula (D′):

wherein,
X represents a chlorine atom, a bromine atom or an iodine atom,
A represents an alkyl group having 1 to 3 carbon atoms,
B represents an alkyl group having 4 to 20 carbon atoms or a cycloalkyl group having 5 to 10 carbon atoms,
R 4 and R 5 each represent a hydrogen atom,
R 7 represents a hydrogen atom and R 6 and R 8 each represent a t-butyl group;

wherein the plurality of X, A, B and R 4 to R 8 may be the same or different at each occurrence.

2. The palladium complex according to claim 1 , wherein A is a methyl group.

3. The palladium complex according to claim 1 , wherein B is an alkyl group having 4 to 20 carbon atoms.

4. The palladium complex according to claim 3 , wherein B is an alkyl group having 4 to 6 carbon atoms.

5. The palladium complex according to claim 4 , wherein B is a tert-butyl group.
