(matrix presented) A Pd(OAc)2/diazabutadiene system has been developed for the catalytic cross-coupling of aryl halides with arylboronic acids. A combination of the diazabutadiene DAB-Cy (1, N,N′-dicyclohexyl-1,4-dizabutadiene) and Pd(OAc)2 was found to form an excellent catalyst for the Suzuki-Miyaura cross-coupling of various aryl bromides and activated aryl chlorides with arylboronic acids.

A highly efficient catalyst for the direct C-H arylation of simple arenes was developed on the basis of a palladium-diimine complex. The developed catalyst exhibited the highest turnover number reported to date for the direct arylation of benzene due to increased stability provided by the diimine ligand. The reaction was also performed using only 2-3 equiv of simple arenes. Mechanistic studies in combination with kinetic measurements, isotope effect experiments, synthesis of possible intermediates, and stoichiometric reactions suggested that this reaction follows a cooperative bimetallic mechanism.

A variety of functionalised biaryls were synthesised on the 20-30 mmol scale by using Knochel type organozinc reagents (organozinc reagents prepared from aryl halides, Zn powder and LiCl) catalysed by PEPPSI (a pyridine enhanced palladium catalyst). The protocol enabled the Negishi reactions to proceed in a smooth, rapid and mild way to give the corresponding products in excellent yields (80 ~ 96%). Sensitive functional groups, such as CN and COOEt groups, were tolerated in the coupling reaction.
