Highly efficient, one‐step synthesis of sulfur‐containing heteroacenes was achieved through palladium‐catalyzed C−S cross‐coupling of bis‐alkynes with thioacetate as hydrogen sulfide surrogate. Heteroacenes consisting of three, five, and seven fused aromatic rings were obtained in a single catalytic step by four‐, six‐, and eightfold C−S bond formation.
通过钯催化的双炔烃与硫代乙酸盐作为硫化氢替代物的C-S交叉偶联,可以高效地一步合成含硫杂芳烃。在一个催化步骤中,通过形成4、6和8倍的C-S键,即可获得由3、5和7个稠合的芳环组成的杂蒽。
