The palladium-catalyzed arylation of 2,2′-diamino-6,6′-dimethylbiphenyl with (variously) bromo-3,5-di-fe/t-butylbenzene, 2-bromopyridine, 2-methylbromopyridine, bromomesitylene, and 2-bromo-4-methylanisole gives three C2-symmetric and three C2-symmetric biaryl-bridged diamino proligands H2L. The subsequent amine elimination (protonolysis) reactions of these with tetrakis(dimethylamido)zirconium yields a range of crystalline complexes [Zr(L)(NMe2)2]. X-ray crystallography reveals molecular structures of five examples with ligated amido, aminopridinato, and aminoanisolato units.
