Processes for preparing β-diketone compound, metal complex thereof and metallic compound
Disclosed is a process for preparing a β-diketone compound such as 2,6-dimethyl-3,5-heptanedione, which comprises reacting an ester compound such as an alkyl isobutyrate with a ketone compound such as 3-methylbutanone in the presence of an alkali metal alkoxide as a catalyst. The process comprises a step 1 in which an ester compound CR1R2R3COOQ is reacted with a ketone compound CR4R5R6COCH2R7 using an alkali metal alkoxide catalyst to give a β-diketone compound CR1R2R2R3COCHR4R5R6. (In the formulae, R7 is hydrogen or an alkyl group of 1 to 4 carbon atoms while others are each independently hydrogen or an alkyl group of 1 to 3 carbon atoms, and at least one of R1 to R6 is hydrogen.)
