The article contains the following contents:
We disclose a silver catalyzed H/D exchange reaction, which can introduce the deuterium atom at the β position of thiophene rings without the assistance of any coordinating groups. The advantages of this reaction include operation in open air, usage of D2O as the deuterium source, good tolerance to a range of functional groups and obtaining high atom% deuterium incorporation. In addition, this H/D exchange reaction is employed for direct deuteration of a thiophene based monomer, which is usually prepared by multistep synthesis from expensive deuterated starting materials. In addition to this study using 2,5-Dibromothiophene, there are many other studies that have used 2,5-Dibromothiophene(cas: 3141-27-3SDS of cas: 3141-27-3) was used in this study.
2,5-Dibromothiophene(cas: 3141-27-3) , is mainly used as pharmaceutical intermediate and synthesis intermediate. 2,5-Dibromothiophene polymerizes by debromination with magnesium catalyzed by nickel compounds to form poly(2,5- thienylene) .SDS of cas: 3141-27-3
