Abstract
A method for converting an N,N-dialkylamide compound into an ester compound includes using a fourth period transition metal complex as a catalyst. The fourth period transition metal complex is obtained by a reaction of a precursor having a fourth period transition metal with a nitrogen-containing compound or a phosphorus-containing compound.

A method for converting an N,N-dialkylamide compound into an ester compound, the method comprising using a fourth period transition metal complex as a catalyst, which is obtained by a reaction of a precursor having a fourth period transition metal with a nitrogen-containing compound or a phosphorus-containing compound.
A fourth period transition metal complex, which is obtained by a reaction of a precursor having a fourth period transition metal with a nitrogen-containing compound or a phosphorus-containing compound in the presence of an alcohol or alkoxide.
A μ-oxo-dimer complex represented by the following general formula (1),
- wherein M represents a fourth period transition metal,
- A represents a carboxylic acid residue, a beta-diketonate, a beta-diketoiminate, or a beta-diketiminate,
- in the case where A represents the carboxylic acid residue, x represents 2, and in the case where A represents the beta-diketonate, beta-diketoiminate, or beta-diketiminate, x represents 1,
- L represents a nitrogen-containing compound or a phosphorus-containing compound, and
- Z represents a lower alkyl group which may have substituent(s), a lower alkoxy group which may have substituent(s), a lower alkenyl group which may have substituent(s), a lower alkynyl group which may have substituent(s), a halo-lower alkyl group which may have substituent(s), a halo-lower alkenyl group which may have substituent(s), a halo-lower alkynyl group which may have substituent(s), a cyclic hydrocarbon group which may have substituent(s), or a heterocyclic group which may have substituent(s),
- the μ-oxo-dimer complex being obtained by a reaction of a metal complex having a ligand selected from the group consisting of beta-diketonates, beta-diketoiminates, and beta-diketiminates, or a carboxylate of a fourth period transition metal, with a nitrogen-containing compound or phosphorus-containing compound, which are added thereto, in the presence of an alcohol or alkoxide.
