An examination was made on Perkin reaction between thiophene aldehydes and p-nitrophenylacetic acid and it was found that 5-nitrothiophene aldehyde which possess nitro group at α-position in thiophene nucleus reacted normally, according to Perkin reaction. However, the one which possess nitro group at other than α-position, reacted according to Perkin reaction, besides bis(p-nitrobenzyl)ketone was formed by the reaction of p-nitrophenyl acetic acid molecules each other.
