Abstract
A series of hexa-and octasubstituted biphenyls containing halogen, amino, nitro, and propylthio substituents were prepared by metal-mediated convergent synthesis from halobenzene precursors. The Pd-assisted CC coupling methods were ineffective in the formation of the Ar-Ar bond except for the synthesis of 1b. All tetra-ortho-substituted biphenyls were prepared via Ullmann coupling reactions. The halogens were introduced ...
