Participants

Reaction Steps

1.94 g of 5-formyl-2,2'-bithiophene was dissolved in 15 ml of ethanol. Then 1.36 g of p-hydroxyphenyl-methyl-ketone was added in, followed by adding KOH (1 g dissolved in H2O and ethanol), the color of the mixture turned into orange. Some crude crystals were crystallized and dissolved later. The reaction solution was placed in a refrigerator overnight. The next day, it was decomposed with ice water and 2 ml of acetic acid were added. The crude product was collected and recrystallized from ethanol, 0.52 g of golden crystal product was thus obtained and the melting point thereof was 202°-205° C.
