Synthesis of substituted polyaryls via sterically hindered double Suzuki cross-couplings

Substituted polyaryls were synthesized successfully via sterically hindered double Suzuki cross-couplings of arylboronic acids with aryl dibromides in the presence of Pd(PPh3)(4) and (KOBu)-Bu-t within a very short time.
