WebBenzo[b]thiophene-2-carbaldehyde can be converted to 2-(1′,2′-epoxyethyl)-benzo[b]-thiophene by reaction with trimethylsulfoxonium iodide and sodium hydride or with diazomethane. However, the 3-carbaldehyde is reported to give the 3-acetyl derivative on treatment with diazomethane ( Scheme 120 ) 〈70AHC(11)177〉 . WebThiophene being an electron-rich heterocycle is directly chlorinated with chlorine gas either in acetic acid or carbon tetrachloride yielding a mixture of polychlorinated products. Chlorination of thiophene with sulfuryl chloride gives a mixture of 2-chloro- and 2,5-dichlorothiophenes. However, chlorination with N-chlorosuccinimide in hexane at reflux …
