Polyaniline supported palladium catalyzed Suzuki–Miyaura cross-coupling of bromo- and chloroarenes in water

Palladium nanoparticle-graphene hybrids as active catalysts for the Suzuki reaction

“…As an efficient catalyst in organic reactions, it can offer the most favorable combination of activity and selectivity [16]. One of the well-known reactions catalyzed by palladium is the Suzuki coupling reaction, which is a powerful and convenient synthetic method in organic chemistry to generate biaryls, conducting polymers, and liquid crystals [17][18][19][20][21].…”

A mechanistic study of cross-coupling reactions catalyzed by palladium nanoparticles supported on polyaniline nanofibers

“…We 47 and others 48,49 previously reported that palladium nanoparticles supported on PANI nanofibers work well for Suzuki coupling in water. In our case, the palladium nanoparticles showed a bimodal distribution with particles of 2 and 50 nm in diameter being present.…”

“…25,27 Our system is also advantageous because it does not need a phase transfer agent like tetrabutylammonium bromide to help with the hydrophobicity of aryl chlorides. 48,49 At the time of our initial report, we hypothesized that a dissolution and redeposition mechanism was operating. Over the past decade, there have been contradicting claims on the true type of catalysis that takes place with palladium nanoparticles.…”

Conducting Polymer-Metal Nanocomposite Coating on Fibers

“…There have been several reports showing conducting polymers can be used as a support for Pd catalyst (Choudary et al, 2006;Houdayer et al, 2005). Kantam et al reported that PANI-supported Pd nanoparticles have high catalytic activity for Suzuki coupling reactions in water and were reused without loss of activity (Kantam et al, 2007). PANI nanofiber-supported Pd nanoparticles with low metal loading (0.05 mol%) are active catalysts for the Suzuki coupling reaction of aryl chlorides with arylboronic acids in water (Gallon et al, 2007).…”
