Direct borylation of benzylic alcohols has been achieved via an iodine-catalyzed process. This transition-metal-free borylation transformation is compatible with various functional groups and provides a practical and convenient method to access important and useful benzylic boronate esters from widely available benzylic alcohols. Preliminary mechanistic investigations indicated that benzylic iodide

The palladium cross-coupling reaction of benzyl halides with diboron 1 yielded structurally diverse pinacol benzylic boronates. Under these reaction conditions, sensitive functionalities such as esters and nitriles are tolerated and the benzylic boronates are obtained in good to high yields.
