C-60-Bodipy dyad triplet photosensitizers as organic photocatalysts for photocatalytic tandem oxidation/[3+2] cycloaddition reactions to prepare pyrrolo[2,1-a]isoquinoline

C-60-Bodipy hybrids exhibiting strong absorption of visible light and long-lived triplet excited states were used as photocatalysts for tandem oxidation/[3+2] cycloaddition of tetrahydroisoquinoline with N-phenylmaleimide to produce pyrrolo[2,1-a]isoquinolines. The reaction is substantially accelerated, compared to that catalyzed by Ru(bpy)(3)Cl-2.
