文摘

We report the first Co-catalyzed borylation of aryl halides and pseudohalides with bis(pinacolato)diboron (B₂pin₂). The synthesis of two new Co(II) complexes of oxazolinylferrocenylphosphine ligands is described. Upon activation with LiMe, the Co complex catalyzes the borylation reactions of aryl bromides, iodides, sulfonates, arenediazonium salts, and even aryl chlorides under mild conditions, providing the borylated products in excellent to moderate yields and with high functional group tolerance.
