<p><P>PROBLEM TO BE SOLVED: To provide a method for producing 3,4-alkylenedioxythiophenes extremely useful as a raw material or an intermediate for a functional material, and 3-halogeno-4-(1-hydroxyalkyloxy)thiophenes being intermediates thereof. <P>SOLUTION: A thiophene is reacted with a diol in the presence of a catalyst containing a copper compound and 8-hydroxyquinoline and a base in an aprotic polar solvent to give a 3,4-alkylenedioxythiophene and a 3-halogeno-4-(1-hydroxyalkyloxy)thiophene represented by formula (4) (wherein X and Y are each independently a halogen atom: R<SP>1</SP>and R<SP>2</SP>are each independently a hydrogen atom, linear, branched or cyclic alkyl which may contain a substituent, aryl which may contain a substituent, heteroaryl which may contain a substituent, hydroxy, carboxy, ester, formyl, cyano, amino or nitro; R<SP>3</SP>to R<SP>6</SP>are each independently a hydrogen atom, linear, branched or cyclic alkyl which may contain a substituent; m is an integer of 0-4). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
