Palladacycles incorporating a carboxylate-functionalized phosphine ligand: syntheses, characterization and their catalytic applications toward Suzuki couplings in water

A series of acetato-bridged [C^X]-type (C = aryl carbanion, X = N, P) palladacycles (1?5) of the general formula [Pd(mu-CH3COO)(C^X)]2 were synthesized as metal precursors via slightly modified procedures. However, in the case of complex 5 with Dpbp (Dpbp = 2?-(diphenylphosphino-kappaP)[1,1?-biphenyl]-2-yl-kappaC) as the supporting C^P ligand, an unexpected dinuclear complex [Pd(mu-CO2)(Dpbp)]2 (6) was obtained as a by-product and structurally determined by X-ray crystallography. The reactions of complexes 1?4 with 2-(diphenylphosphino)benzoic acid conveniently afforded four carboxylate-functionalized phosphine complexes [Pd(C^N)(Dpb)] (Dbp = 2-(diphenylphosphino-kappaP)benzoato-kappaO, 7?10), two of which (9/10) are newly synthesized in the present work and have been fully characterized. A comparative catalytic study revealed that complex [Pd(Ppy)(Dpb)] (7) (Ppy = 2-(2-pyridinyl-kappaN)phenyl-kappaC) is the best performer in Suzuki cross-couplings in H2O. In addition, complex 7 exhibits much better catalytic activity compared to the non-functionalized phosphine equivalent [Pd(OAc)(PPh3)(Ppy)] (11), which clearly indicates the superiority of incorporating a carboxylate-functionalized phosphine ligand into the palladacycles. A preliminary mechanistic study uncovered a different precatalyst initiation pathway compared to other known analogues of catalyst precursors.
