Abstract
Disclosed herein is method for producing an iron dinuclear complex having two iron atoms bonded to each other via one oxygen atom and a ligand structure containing a Schiff base, a method which can produce an ester compound in high yield by the transesterification of an alcohol compound with a carboxylate ester even in the case where the raw material alcohol has a tertiary hydroxyl group which is usually difficult to esterify by transesterification, and a method which can produce a wholly esterified compound by transesterification catalyzed by an iron complex.
Claims17
A method for producing an iron complex represented by the general formula (4) or (5) below,
- the method comprising:
- (I-1) mixing in the presence of water an iron salt and a compound represented by formula (1), to obtain a precursor solution:
- and
- a step (I-2) mixing the precursor solution with a compound represented by formula (2) or (3):
- wherein:
- R1, R2, R3, R4, R5, R6 and R7 are each independently a hydrogen atom, an alkyl group, a monovalent alicyclic group or a monovalent aromatic ring group,
- with the proviso that at least one pair of R1 and R2, R2 and R3, and R4 and R5 may be bonded to each other to form a ring.
