Convenient Synthesis of a Tetrathienyl Dendritic Core
摘要:
Toward the goal of hole-conducting materials, we present the synthesis of a tetrabrominated-tetrathienyl derivative for use as a four-branch core in dendrimer synthesis. Commercially available 2-thienyllithium was reacted with methyl formate to give 2,2'-dithienyl-methanol and upon acidic workup results in 2,2',2'',2'''-oxybis(methanetriyl)tetrathiophene. The tetrathienyl product underwent regioselective tetrabromination with N-bromosuccinimide at the thienyl-5-positions in 68% overall isolated yield.
