Palladium-catalyzed benzylation of N-Boc indole boronic acids

The direct benzylation of indole 2-boronic acid can be efficiently achieved using trans-PdBr(N-Succ)(PPh₃)₂, alleviating the need for strong bases or toxic organotin reagents. Under these reaction conditions substituted indole-2-boronic acids and substituted benzyl bromides are cross-coupled to afford aryl(indolo)methanes in good yield.
