Electrophilic gold(I) catalyst 6 competes with GaCl(3) as the catalyst of choice in the synthesis of fluoranthenes by intramolecular hydroarylation of alkynes. The potential of this catalyst for the preparation of polyarenes is illustrated by a synthesis of two functionalized decacyclenes in a one-pot transformation in which three C-C bonds are formed with high efficiency.
亲电金 (I) 催化剂 6 与 GaCl(3) 竞争作为通过炔烃分子内加氢芳基化合成荧蒽的首选催化剂。这种催化剂用于制备聚芳烃的潜力通过在一锅转化中合成两个官能化十环烯来说明,其中三个 CC 键高效地形成。
