nium hexafluorophosphate [Cp*Ru(NCMe)3+ PF6−] and para‐toluenesulfonic acid catalysts. These allyl ketones undergo direct regioselective hydroarylation/Friedel–Crafts reaction to introduce an electron‐rich aryl group at the γ‐position in the presence of ligand‐free silver triflate (AgOTf) catalyst. Both catalytic reactions take place with atom economy and provide an alternative to the synthesis of
β的区域选择性合成,从末端炔γ不饱和酮是由三协同作用来实现(乙腈)六氟磷酸pentamethylcyclopentadieneruthenium的[Cp *茹(NCMe)3 + PF 6 - ]和对甲苯磺酸催化剂。这些烯丙基酮在无配体的三氟甲磺酸银(AgOTf)催化剂存在下,直接进行区域选择性加氢芳基化/ Friedel-Crafts反应,在γ位引入富电子芳基。两种催化反应都是在节约原子的条件下进行的,为合成各种烯丙基酮和γ-芳基化酮提供了另一种选择。
