The results of a ligand-free Pd(OAc)2-catalyzed Suzuki-Miyaura C-C coupling performed at room temperature under aerobic conditions are presented. It was found that the use of an ethylene glycol monomethyl ether/H2O mixture as the solvent resulted in very rapid reactions of aryl bromides with arylboronic acids. As a matter of fact, under optimized conditions, some substrates were converted quantitatively in less than 1 min with exceptionally high TOF values. For example, the reaction between 4-methoxyphenylboronic acid and bromobenzene afforded 4-methoxybiphenyl in 30 s with TOF = 180000 h-1. Furthermore, the reaction tolerates a wide range of functional groups and can be successfully applied to heteroaryl bromides such as 2-bromopyridine and 5-bromopyrimidine. Interestingly, also an activated aryl chloride such as 1-chloro-4-nitrobenzene reacted quantitatively with phenylboronic acid at 373 K. Wiley-VCH Verlag GmbH & Co. KGaA, 2009.

A methodology for a sequential palladium-catalyzed cross-coupling procedure consisting of borylation, the Suzuki reaction and amination has been developed for the assembly of molecules with multi-aryl backbones. The linchpin of this development is the meta-terarylphosphine ligand, Cy*Phine, which has been employed as an air- and moisture-stable precatalyst, Pd(Cy*Phine)2Cl2, to improve the efficiency of one-pot borylation–Suzuki reactions. Additionally, the reactivity of the Pd-Cy*Phine system could be tuned to furnish a one-pot, borylation–Suzuki reaction–amination (BSA) cross-coupling treble. The methodology successfully integrated complementary conditions for three distinctly different and modular reactions. Average yields of 74–94% could be achieved for each segment that cumulatively afforded 50–84% yield over the entire three-step sequence in a single pot. (Figure presented.).
