Chen, Xiaohong; Zheng, Guangfan; Song, Guoyong; Li, Xingwei published an article in 2018, the title of the article was Rhodium(III)-Catalyzed Synthesis of Cinnolinium Salts from Azobenzenes and Diazo Compounds.Recommanded Product: 65417-22-3 And the article contains the following content:
A Rh(III)-catalyzed C-H activation of azobenzenes in the coupling with diazo compounds has been realized, providing a straightforward strategy to access functionalized cinnolinium triflates, e.g., I in high yields. This protocol features silver free mild reaction conditions and compatibility with diverse functional groups. The coupling proceeds via initial Rh(III)-catalyzed C-H alkylation, followed by zinc triflate-mediated cyclization, where zinc triflate acts as a Lewis acid as well as a triflate source. The experimental process involved the reaction of Methyl 2-methyl-1H-indole-3-carboxylate(cas: 65417-22-3).Recommanded Product: 65417-22-3
