Synthesis of [60]fullerene-fused dihydrobenzooxazepines via the palladium-catalyzed oxime-directed C–H bond activation and subsequent electrochemical functionalization†
Abstract
The palladium-catalyzed heteroannulation reaction of [60]fullerene with oximes has been exploited to accomplish the synthesis of the unprecedented seven-membered [60]fullerene-fused dihydrobenzooxazepines. In addition, the formed [60]fullerene-fused dihydrobenzooxazepines can be further electrochemically transformed into 1,2,3,4- and 1,2,3,16-adducts of [60]fullerene.
