In our reaction protocol, we discovered that N-heterocyclic nucleophiles such as 2chlorobenzimidazole can be directly coupled to an arene such as mesitylene, resulting in a yield of 52% of 30. When the catalytic activity was checked without any additional additives, we found that our catalytic system can even deliver nearly the same yield without any additional additives such as LiClO4. The coupling between benzene and 1H-pyrazole-4-carboxylate provides 7 with 87% and 80% yield with and without LiClO4 respectively. Additionally, the coupling of mesitylene and 1H-pyrazole-4-carboxylate provides 75% and 71% yield of 24 with and without LiClO4 respectively.
