Electrochemical ring-contraction synthesis of [60]fullerene-fused indanes from [60]fullerene-fused tetrahydroisoquinolines

The synthesis of [60]fullerene-fused indanes was developed via an electrochemically triggered, trace-oxygen-mediated ring contraction of [60]fullerene-fused tetrahydroisoquinolines, followed by direct functionalization at the nitrogen atom with trifluoroacetic acid or electrophiles....
