A dithizone-functionalized polystyrene resin-supported Pd(II) complex as an effective catalyst for Suzuki, Heck, and copper-free Sonogashira reactions under aerobic conditions in water

Diethylenetriamine-functionalized single-walled carbon nanotubes (SWCNTs) to immobilization palladium as a novel recyclable heterogeneous nanocatalyst for the Suzuki–Miyaura coupling reaction in aqueous media

“…From Table 2, it can be seen that the present catalyst exhibited higher conversions and yields compared to the other reported systems [20,[32][33][34][35].…”

Pd complex of an NNN pincer ligand supported on γ-Fe2O3@SiO2 magnetic nanoparticles: a new catalyst for Heck, Suzuki and Sonogashira coupling reactions

“…Moreover, most of the reported methods are amenable only for the cross-coupling reactions of aryl iodides and bromides. 6 Bis(imino)pyridines (BIP) with the central nitrogen donor and flanking imine arms are known as NNN tridentate pincer ligands, which coordinate easily with transition metals such as Mn, Zn, Gd, Ni, Co and Fe to form metal complexes. 7 These metal complexes have mainly applied as highly active and selective catalysts for the oligo-and polymerization of olefins.…”

Solid-Supported Palladium Catalysts in Sonogashira Reactions: Recent Developments

“…The catalyst was recycled for five runs in the coupling between iodobenzene and phenylacetylene, observing a decrease in the final yield from 99% to 90%. In addition, the dithizone-functionalized supported Pd(II) complex 10 has proved effective as catalyst in the copper-free Sonogashira reaction between aryl iodides and bromides and terminal acetylenes, using piperidine as base in water as solvent at room temperature ( Figure 3) [26]. The recycled catalyst was reused for five runs observing almost no loss of effectivity.…”
