文摘

A transition-metal-free oxidative dehydrogenative coupling reaction has been developed for the direct construction of novel C₆₀-fused tetrahydrocarbazoles, dibenzothiophenes, benzothiophenes, and dibenzofurans. This new carboannulation reaction features high atom economy, operational simplicity, broad substrate scope, and excellent functional-group tolerance and provides a convenient access to a scarce class of fullerene derivatives.
