The NCN-Type Pincer Complex of Palladium(II) with a 2,6-Bis(2-pyridyl)-4-tert-butylbenzene Tridentate Ligand: Synthesis, Structure and Catalytic Activity in the Mizoroki-Heck Reaction

The reaction of 1-bromo-4-tert-butyl-2,6-diiodobenzene with 2-pyridylzinc chloride in the presence of catalytic Pd(PPh 3 ) 4 afforded an NCN-type pincer palladium(II) complex with two pyridine donors.The structure of the complex was determined by X-ray crystallography.The complex was found to catalyze the Mizoroki-Heck reaction at 250 °C under aerobic conditions.
