Abstract
An objective of the present invention is to provide a process for producing 4-carbonyl oxyquinoline derivatives useful as agricultural and horticultural pesticides and fungicides. The objective can be attained by a process for producing 4-carbonyl oxyquinoline derivatives represented by general formula (1), the process including reacting a quinolone derivative with a halogenated compound or an acid anhydride in the presence of a phase transfer catalyst and a base.
