Thiophene derivative siv los ua electropolymerization monomer hauv kev tshawb fawb polymer. Thiophene, 2-methyIthiopheney thiab 3-methylthiophene ua raws li inhibitors rau polymerization ntawm trichlorethylene hauv cov kuab tshuaj siv rau degreasing hlau thiab txhuas, hais tias polymerization tau catalyzed los ntawm kev sib cuag ntawm cov kuab tshuaj nrog cov hlau. Bonz, xyoo 1885, qhia txog kev tsim dichloroethylthiophene los ntawm chlorination ntawm 2-ethylthiophene thaum txias. Puas yog Opolski tau kawm txog chlorination ntawm 2- thiab 3-methylthiophenes, 2-ethyl- thiab 2-butylthiophene thiab tshaj tawm qhov tsis sib xws rau monochloro derivatives. Voerman tau chlorinated 3-methylthiophene nyob rau sab saw nrog phosphorus trichloride nyob rau hauv tshav ntuj, tab sis lub nplhaib sib txuas chlorination feem ntau. 3-Methylthiophene muab qhov tshwj xeeb cov tshuaj tiv thaiv nrog alkyl- lossis arylsodium uas qhov kev hloov pauv tshwj xeeb hauv 5 txoj haujlwm ntau dua li qhov xav tau 2-txoj haujlwm.
