Pre-synthesized δ-CF3-δ-aryl-disubstituted para-quinone methides bearing δ-substituents were identified as isolable and storable substrates for 1,6-arylation reactions. A broad range of electron-rich arenes and heteroarenes participated in the arylation process, furnishing a wide array of unsymmetrical CF3-substituted triarylmethanes in high efficiency. The mild and expeditious protocol exhibited broad scopes of both arene and para-quinone methide components.

带有 CF3 取代的全碳四元立体中心的不对称三芳基甲烷的合成：δ-三氟甲基取代的对醌甲基化物的 1,6-芳基化

预先合成的带有 δ-取代基的 δ-CF3-δ-芳基-二取代对醌甲基化物被鉴定为 1,6-芳基化反应的可分离和可储存底物。广泛的富电子芳烃和杂芳烃参与了芳基化过程，高效地提供了一系列不对称的 CF3 取代的三芳基甲烷。温和而迅速的方案展示了芳烃和对醌甲基化物组分的广泛范围。
