Title: METHOD FOR PRODUCING IRON COMPLEX AND METHOD FOR PRODUCING ESTER COMPOUND USING IRON COMPLEX
Abstract:
Provided are: a method for easily producing, with a high yield, an iron binuclear complex having a structure in which two iron atoms are bonded together through one oxygen atom, and a ligand structure containing a Shiff base, in the molecule; a method for producing an ester compound with a high yield by transesterification of a raw material with a carboxylic acid ester, even when the raw material is an alcohol compound having a tertiary hydroxy group, which is normally difficult to undergo transesterification; and a method for producing an ester compound with a high yield by transesterification of an alcohol compound having a plurality of hydroxy groups using an iron complex as a catalyst, wherein all of the hydroxy groups of the alcohol compound are esterified in the ester compound. A method for producing an iron complex represented by general formula (4) or (5), comprising a step (I-1) for formulating a precursor solution by mixing an iron salt and a compound represented by general formula (1) in the presence of water, and a step (I-2) for mixing the precursor solution and a compound represented by general formula (2) or (3), and a method for producing an ester compound, comprising a step (IV) for performing transesterification of a carboxylic acid ester and an alcohol compound in the presence of the iron complex.
