Palladium-Catalyzed Cross-Coupling Reactions of Bromo-Substituted Group 4 Metallocenes
摘要:
Pd-catalyzed Negishi reactions of Zr and Hf complexes bearing eta(5)-4-bromo-2-methylindenyl and eta(5)-2-bromindenyl ligands with MeZnCl and varios aryl- and hetero-arylzinc reagents (RZnCl) give in high yields the respective complexes bearing eta(5)-4-R-2-methylindenyl and eta(5)-2-R-indenyl ligands, respectively.
