Chlorosuccinimide → 5-Chloro-2,3-bis(4-methoxyphenyl)thiophene

Participants

Reaction Steps

A solution of N-chlorosuccinimide (2.92 g, 22 mmole) in 50 ml methylene chloride was added to a solution of 2,3-bis(4-methoxyphenyl)thiophene (5.92 g, 20 mmole) in 70 ml methylene chloride and 75 ml acetic acid. After 45 minutes at room temperature, the reaction mixture was heated at reflux for 18 hours. The cooled reaction mixture was then concentrated in vacuo.
