Manganese-catalyzed carbonylation of alkyl iodides
… the formation of substituted biphenyls and terphenyls, however only two ortho-substituents are tolerated in this transformation. The studies reportd herein aimed at the synthesis of tri- and tetra substituted biaryls, since they are important precursors to biaryl phosphine ligands. The …

High Birefringence And Low Viscosity Liquid Crystals
… Some (2,3) laterally difluorinated biphenyls, terphenyls and tolanes are selected for this study. Due to the strong repulsive force between LCs and alignment layer, (2,3) laterally difluorinated terphenyls and tolanes do not align well in a VA cell resulting in a poor contrast ratio for the LC …

Synthesis and analysis of polyphenyl compounds and their derivatives
… of the partially and fully hydrogenated terphenyls. The focus is the synthesis of para substituted three-ring structures, from fully aromatic p-terphenyl to fully saturated p-tercyclohexyl and the intermediary partially reduced compounds. These compounds are successfully synthesised. The …
