The construction of ring-fluorinated seven membered carbocycles was readily achieved via the domino S(N)2'-type/SNV reaction between 2-(trifluoromethyl)-1-alkenes and 1,4-carbodianions. The S(N)2'-type reaction of 2-(trifluoromethyl)-1-alkenes with 2,2'-diceriobiaryls generated the intermediary 1,1-difluoro-1-alkenes bearing a monoceriobiaryl moiety, which in turn underwent intramolecular SNV reaction to afford fluorinated 5H-dibenzo[a,c][7]annulenes.
