New Air-Stable Catalysts for General and Efficient Suzuki−Miyaura Cross-Coupling Reactions of Heteroaryl Chlorides

New air-stable PdCl2{P t Bu2(p-R-Ph)}2 (R = H, NMe2, CF3,) complexes represent simple, general, and efficient catalysts for the Suzuki−Miyaura cross-coupling reactions of aryl halides including five-membered heteroaryl halides and heteroatom-substituted six-membered heteroaryl chlorides with a diverse range of arylboronic acids. High product yields (89−99% isolated yields) and turn-over-numbers (10 000 TON) are observed.
