Abstract

Arylboronic acids, boronate esters, and potassium trifluoroborate salts are versatile reagents for modular organic synthesis. In cross-coupling protocols, they are important nucleophilic partners in the preparation of a wide range of structurally similar, yet diversified biaryl backbones.[1, 2] Arylboronic acids and esters are usually prepared through bromomagnesium or-lithium exchange followed by trapping with trialkylborates. Although ...
