International audienceA series of dehydroacetic acid difluoroboron complexes functionalized by a Ph ring or an electroactive core (tetrathiafulvalene or ferrocene) were synthesized and characterized. The redox properties of these derivs. have been analyzed by cyclic voltammetry and the mol. structures of some of the difluoroboron complexes are presented and discussed. The photophys. properties of selected difluoroboron complexes were detd. in soln. and in the solid state evidencing an AIEE (Aggregation Induced Enhancement Emission) phenomenon
A two-step isoindolone synthesis has been achieved by using an Ugi/oxidative vicarious nucleophilic substitution sequence starting from 3-nitrobenzoic acid and aromatic aldehydes. Loss of the amido group was observed as well as a further oxidative process towards hydroxyisoindolone derivatives after prolonged stirring open to the atmosphere.
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.
