Novel bispinacolborane‐N,N′‐bis(octyl)‐3,4,9,10‐Perylene (cas 198-55-0)tetracarboxylic acid bisimide (PBI) was synthesized in high yield. The title compound is a key intermediate in the preparation of PBI aryl derivatives through Suzuki cross‐coupling by using a large variety of easily accessible aryl halides. The benign effect of a nonpolar solvent, mild base, and high reaction temperature on the borylation reaction was studied, and the reaction conditions were optimized accordingly. To demonstrate the potential and flexibility of the proposed building block, two corresponding bisarylperylene bisimides were prepared in high yields.
