You may substitute bromine with NBS (N-bromo succinimide). NBS provides low level of bromine concentration, therefore, it is not very harsh. However, everything depends on the substrate reactivity. Good luck. Tilak

Subject: [DCHAS-L] Alternatives to Bromine

 

Hi All,

I was hoping I could gather some information from this listserv regarding replacement options for Bromine in Bromination reactions. We'd like to replace bromine with an alternative (or alternatives) for our brominations in our undergraduate organic synthetic experiments as it's a pain to store and handle properly. Could anyone provide any suggestions or direct me to key resources regarding alternatives to bromine for brominations?

Your feedback would be extremely helpful!
