Pentafluorinated phenyl-monohydro[60]fullerenes [C 60 (Ar f ) 5 H] are synthesized in good yields via reaction of the corresponding fluorinated phenyl copper reagent, itself prepared in situ from the fluorinated phenyl Grignard reagent (Ar f MgBr) and copper(I) bromide-dimethyl sulfide complex, with [60]fullerene (C 60 ) in 1,2-dichlorobenzene under a nitrogen atmosphere.
A facile and efficient synthesis of fluorine-containing polyhydrobenzoacridines was accomplished by a three-component coupling of fluorinated aldehyde, α-naphthylamine, and 1,3-cyclohexanedione or dimedone under microwave irradiation and solvent-free conditions without catalyst. All new compounds were obtained in moderate to good yields and characterized by standard spectroscopic methods.
A facile and efficient synthesis of 14-fluorophenyl-14H-dibenzo[a,j]xanthenes has been developed by one-pot condensation of fluorinated benzaldehydes with β-naphthol in the presence of p-TSA•H 2 O under microwave irradiation and solvent-free conditions. These products are conveniently oxidized to 14-fluorophenyl-14-hydroxydibenzo[a,j]xanthenes by PbO 2 in acetic acid in good yields.
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.
