Iron-catalyzed trifluoromethylation of vinylcyclopropanes: facile synthesis of CF3–containing dihydronaphthalene derivatives†
Abstract
An efficient Fe(II)-catalyzed trifluoromethylation of vinylcyclopropanes was successfully developed. A series of CF3-containing dihydronaphthalene derivatives were prepared in moderate to high yields (up to 96%) under mild reaction conditions using the Togni reagent as the CF3 source.
