A Simple Synthesis of 5,5′‐Dibromo‐2,2′‐bifuran, the First 5,5′‐Dihalogenated 2,2′‐Bifuran Derivative Bromination of furan with N ‐bromosuccinimide in the presence of HgC1 2 and Et 3 N in chloroform gave 5,5′‐dibromo‐2,2′‐bifuran ( 3 ) in good yield. Symmetrical dibrominated polyfuran derivatives of type 4 were also obtained as by‐products.
