Rigid polyaromatic dialdehydes: biphenyl-4,4'-dialdehyde and its longer analogues have been synthesized in high yields by using the Suzuki-Miyaura cross-coupling reaction. In addition, a novel procedure for a gram-scale preparation of biphenyl-4,4'-dicarbaldehyde from commercially available 4,4'-bis(chloromethyl)biphenyl has been developed.
