Top of the one‐pots! The first palladium‐catalyzed borylation of aryl tosylates and mesylates is described. The reaction conditions are mild and provide excellent functional‐group compatibility (e.g., R=CN, CHO, COOMe, C(O)R, NH2, or NH‐indole; see scheme). Pd/MeO‐CM‐phos allows one‐pot sequential reactions in the preparation of unsymmetrical biaryls.
一锅之巅!描述了芳基甲苯磺酸盐和甲磺酸盐的第一个钯催化的硼化反应。反应条件温和,并具有出色的官能团相容性(例如,R = CN,CHO,COOMe,C(O)R,NH 2或NH-吲哚;请参见方案)。Pd / MeO-CM-phos可在不对称联芳烃的制备中进行一锅法依次反应。
