We report herein a new approach for the synthesis of tellurium-bridged aromatic compounds based on the sequential electrophilic telluration of C(sp)-Zn and C(sp)-H bonds with tellurium(iv) chlorides. A combination of transition metal-catalyzed (migratory) arylmetalation of alkynes and sequential telluration allows for the expedient construction of a library of functionalized benzo[]tellurophenes. Furthermore, a variety of heteroarene-fused benzotellurophenes and other novel tellurium-embedded polycyclic aromatics can be readily synthesized from the corresponding 2-iodoheterobiaryls.
我们在此报告一种基于用四氯化碲对C(sp)-Zn键和C(sp)-H键进行顺序亲电碲化反应来合成碲桥连芳族化合物的新方法。过渡金属催化的炔烃（迁移）芳基金属化反应与顺序碲化反应相结合，能够便捷地构建功能化苯并[]碲吩文库。此外，从相应的2-碘代杂二芳基可以很容易地合成各种杂芳基稠合苯并碲吩和其他新型含碲多环芳烃。
