transformations of CF3 group with nitro compounds into amides or Schiff bases employing Ytterbia as a catalyst. This process proceeds via C−F bond activation, accompanied with utilisation of Si-based reductants/oxygen scavengers – reductants of the nitro group. The scope and limitations of the disclosed methodologies are thoroughly studied. To the best of our knowledge, this work is the first example of

bromomalonate to give the corresponding N-aryl-C,C-dimethoxycarbonylnitrones (4–6). Treatment of C,C-dimethoxycarbonyl-N-( 1-naphthyl)nitrone (4) with acetylene compounds (dimethyl acetylenedicarboxylate, methyl 2-butynoate or ethyl phenylpropiolate) caused 1,3-dipolarcycloaddition to furnish the corresponding 1H-benz[g]indolines (7a-c). In a similar manner, the reactions of nitrones 5 and 6 with acetylene compounds
