Dimethyl Sulfoxide → 3-(4-Hydroxyphenyl)-1-phenylprop-2-en-1-one

Participants

Reaction Steps

10 g of methoxy chalcone and 2.05 g of sodium cyanide are dissolved into 100 ml of dimethyl-sulfoxide, and then reacted during 24 hours. After the reaction, the reacted solution is mixed with chloroform and stirred together with distilled water so as to extract impurities. After removing the solution phase, the solution is decompressed at a room temperature in order to eliminate chloroform. After recrystallizing the remained solid phase in methanol, the solution is dried under vacuum, thus obtaining side chain 4-hydroxychalcone for photoreaction.
