The behavior of different aromatic and heteroaromatic rings in a non-phenolic oxidative biaryl coupling process using PIFA [phenyliodine(III)bis(trifluoroacetate)] as the source of hypervalent iodine was studied. The experiments carried out led us to the construction of the basic skeletons of phenanthrene, naphthothiophene and pyrroloisoquinoline tricycles in a short and efficient way. The study was also extended to the preparation of phenanthroid-fused thiazoles.
