amount of trifluoromethanesulfonic acid in 1,1,1,3,3,3-hexafluoropropan-2-ol. Five substrates were successfully employed in this protocol to afford ortho-fused six-hexagon benzenoids with high selectivities and in excellent yields.
带有两个由亚甲基-2,1-亚苯基连接的缩醛部分的萘使用催化量的三氟甲磺酸在 1,1,1,3,3,3-六氟丙-2-醇中进行区域选择性串联环芳构化。在该协议中成功使用了五种底物,以提供具有高选择性和优异产量的邻位融合六六边形苯类。
