Abstract

View all references A suitable catalyst system varied in the substrates as mentioned above. During the course of our investigations, we examined a synthesis of benzylboranes 3 focusing on what kind of transition metals catalyzed a borylation of benzyl halides 1. We here report the borylation of 1 with pinacolborane 2 as a boron source (Eq. 1). ...
