Abstract
NEW MATERIAL:A 2,3-dihydrozenzofuran derivative shown by the formula I (R1 is alkyl which may have alkoxycarbonyl, acylamino, etc. as a substituent group; R2 is H or alkyl; R3-R5 are H, alkoxy, alkyl, halogen), and a benzoquinone derivative shown by the formula II.
EXAMPLE: 5-Hydroxyl-2,6-dimethyl-2,3-dihydrobenzofuran-3-carboxylic acid methyl ester and 3-hydroxy-2-(5-methyl-1,4-benzoquinone-2-yl)butyric acid methyl ester.
USE: An intermediate for organic synthesis. A compound shown by the formula II is effective for dyeing fibers into orange.
PROCESS: A partially novel compound shown by the formula III is irradiated with light rays having a wave length of 380W500nm in a solvent for tens of minutes to several hours to give a compound shown by the formula I. A compound shown by the formula II is obtained by oxidizing the compound shown by the formula I with an oxidizing agent (e.g., iron chloride) in a solvent.
