Phenylboronic Acids

The environmentally benign Suzuki cross-coupling reaction was developed by using ScCO2(Supercritical CO2) instead of traditionally organic solvent. In the paper the compound phenylferrocene was synthesized by the Suzuki cross-coupling reaction of iodoferrocene and phenylboronic acids in ScCO2/PEG (polyethylene glycol) with excellent yield ratio in the presence of ligand-free Pd/C catalyst and K2CO3.1.5H2O as base. The Pd/C catalyst can be reused by simply washing sequence and CO2can be recycled after depressurization. The catalytic reaction conditions were optimized in the reaction using ScCO2as solvent.

Precursor Decomposition

This paper describes the synthesis of Pd-containing catalysts based on nonfunctionalized hypercrosslinked polystyrene via impregnation with Pd acetate. Developed Pd nanoparticulate catalyst allowed achieving conversion of aryl halide up to 90% in Suzuki cross-coupling reaction under mild conditions and at the absence of phase-transfer agents. During the selective hydrogenation of triple C-C bond of 2-methyl-3-butyn-2-ol, up to 96% selectivity with respect to corresponding olefinic alcohol was found at 95% conversion. The influences of the procedure of catalyst synthesis like precursor decomposition and reductive activation method on Pd nanoparticle formation are discussed.

High Yields

A regiospecific palladium-catalyzed cross-coupling reaction using the operational equivalent of the dianion 1,3-dilithiopropyne, with aromatic iodides is reported. This reaction gives high yields of 1-propyn-1-yl-benzenes and 2-(propyn-1-yl)thiophenes in the presence of catalytic amounts of palladium(0) or (II) and stoichiometric amounts of copper iodide. No terminal alkyne or allene isomers were detected. Reaction conditions were very mild and several functional groups were tolerated.
