Preparation of arylboronic and diarylborinic acids from potassium aryl(fluoro)borates
摘要
A series of acids ArB(OH)2 and Ar2BOH with an electron-withdrawing aryl group were obtained from the corresponding borates K[ArBF3] and K[Ar2BF2] by the action of MX3 (M = B, Al; X = Cl, Br) and subsequent hydrolysis.
