Chen, Weiqiang;Li, Hui-Jing;Cheng, Yun-Fei;Wu, Yan-Chao research published 《 Direct C2-arylation of N-acyl pyrroles with aryl halides under palladium catalysis》, the research content is summarized as follows. C2-arylation of N-acyl pyrroles with aryl halides was developed for the first time using Pd(PPh3)4 as a catalyst in combination with Ag2CO3 under air, which allowed the application of a good compatibility catalytic system. This protocol provided a straightforward method for the preparation of valuable arylated pyrroles in moderate to good yields under the standard conditions with good substrate tolerance. Interestingly, while N-benzoyl pyrroles reacted well, the use of substrates with a thiophene or furan ring indicated that the thiophene and furan rings were more reactive than pyrrole for the present catalytic system.
