Borenium does it direct: A boron analogue of the Friedel-Crafts reaction uses inexpensive catecholatoborenium cations that are sufficiently electrophilic to borylate arenes by electrophilic aromatic substitution. The direct arene borylation proceeds with high regioselectivity for a range of anilines, N-heterocycles, and thiophenes. Subsequent one-pot transesterification provides the synthetically useful pinacol boronate esters (see scheme).
