Palladium-Catalyzed Regioselective C–S Bond Cleavage of Thiophenes
摘要:
Herein, a Pd-catalyzed reaction of simple and diverse bromothiophenes with alkynes via regioselective C-S bond activation is reported. This provides a new approach to prepare sulfur-based heterocycles and fulvenes.

Reaction of 2,5-dibromothiophene dioxide with two equivalents of tetracyclone yields a heptaphenyl triphenylene, presumably by double Diels-Alder addition followed by fragmentation and rearrangement of the resulting radicals.
