Unexpected Formation of Hexasubstituted Arenes Through a Twofold Palladium-Mediated Ligand Arylation

A rearrangement reaction of biarylphosphine-supported Pd(II) complexes was employed to synthesize 1,3,5-triaryl 2,4,6-triisopropylbenzene compounds, a class of molecules that has not previously been reported. The strain of the central hexasubstituted ring was investigated via X-ray crystallography.
