title: Synthesis of [60]fullerene-fused tetrahydrobenzooxepine and isochroman derivatives via hydroxyl-directed C-H activation/C-O cyclization.
abstract: The palladium-catalyzed hydroxyl-directed C-H activation/C-O cyclization reaction of [60]fullerene with 2-phenylethyl alcohols and benzyl alcohols afforded [60]fullerene-fused tetrahydrobenzooxepine and isochroman derivatives in up to 43% yield. A plausible reaction mechanism is proposed, and the electrochemistry was also investigated.
