1,3-Phenylene-bis-(1H)-tetrazole Pincer Ligand for Palladium-Catalyzed Suzuki
Reactions of Arylhalides with Arylboronic Acids. — The newly
08- 090 Cross-Coupling
reported tetrazole ligand combined with palladium is very stable at high temperatures,
which allows the Suzuki-crosscoupling of otherwise less reactive substrates like aryl
chlorides (II) and bromides (IV). The resulting coupling products (III), (V) and (VII)
are obtained in good yields. — (GUPTA, A. K.; RIM, C. Y.; OH*, C. H.; Synlett
