The complexes (Cy2PC3H6PCy2)Ni(η2-arene) (arene = toluene (3), naphthalene (4)) have been synthesized and studied in detail. Displacement reactions of the toluene ligand afford the complexes (Cy2PC3H6PCy2)Ni(η2-styrene) (5), (Cy2PC3H6PCy2)Ni(PhCN) (6), (Cy2PC3H6PCy2)Ni(CO)2(7), (Cy2PC3H6PCy2)Ni(PPh3) (8), (Cy2PC3H6PCy2)Ni(PCy3) (9), {(Cy2PC3H6PCy2)Ni}2(μ-H)2(10), (Cy2PC3H6PCy2)Ni(η2-CO2) (11), and [(Cy2PC3H6PCy2)Ni]2(μ,η2-1,5-COD) (12). The relative rates of ArCl oxidative addition at Ni complexes 3, 4, 6, 8, and 12have been evaluated experimentally, and the mechanism has been calculated by DFT. Complexes 3and 4are efficient catalysts for the Suzuki–Miyaura reaction between chloroarenes and Ar′B(OH)2. |
