A rhodium catalyzed direct regioselective oxidative annulation by double C-H activation is described to synthesize highly substituted quinolones from pyridones. The reaction proceeds at mild conditions with broad scope and wide functional group tolerance. These novel quinolones were explored to recognize nitroaromatic compounds.
A simple and readily synthesized BODIPY based fluorescent chemosensor has been developed for the selective and sensitive detection of Cd2+ ions up to a submicromolar level in aqueous media.
A series of highly emissive arylene–vinylene terpyridine conjugates have been developed for the detection of nitroaromatic (NAC) explosives as efficient and reusable fluorescent probes.
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.
