We have developed a convenient and efficient approach to 1H‐indazoles in one pot under air atmosphere, using additive intermediates of Grignard reagents to 2‐aminobenzonitriles via a FeCl3/Bpy catalyzed N–N coupling. Besides, such intermediates could react with esters in one pot to yield quinazolines promoted by BiCl3/Ph3P. Both 1H‐indazoles and quinazolines were prepared in good to excellent yields. The possible mechanisms for the formation of 1H‐indazoles and quinazolines were proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
