3-bromo-4-thienylmanganese bromide

We reported a facile synthesis of 3-bromo-4-thienylmanganese bromide and 4-substituted 3-thienylmanganese bromides via the direct oxidative addition... 

As shown in Table 8.18, 3-bromo-4-thienylmanganese bromide was formed as a major product from the reaction of 1 equiv of 3,4-dibromothiophene and 2equiv of Mn [47]. This reagent easily underwent a cross-coupling reaction with acid chlorides and aryl iodides. According to the high-resolution mass spectra of the products of entries 1,4,5, and 6 in Table 8.18, the second bromine atom of the thiophene ring is still retained.
