Substituted cyclopentadieneones have received much interest lately, functioning as important building blocks in several new syntheses of polyaromatic materials. 1 For instance, tetraarylcyclopentadieneones (tetracyclones) have been employed extensively in the preparation of large graphite disks. 2 Diarylcyclopentadieneones have been used to prepare soluble, blue light-emitting PPV-type polymers3 and in the synthesis of ...
