A new polymer containing phosphorus and nitrogen ligands was successfully synthesized, characterized and used for the stabilization of highly monodispersed palladium nanoparticles having an average diameter of 2-3 nm. The thermally stable heterogeneous catalyst was successfully applied in Suzuki-Miyaura and copper-free Sonogashira-Hagihara coupling reactions of aryl halides under low palladium loading conditions. Reactions were proceeded in neat water without using any organic co-solvents. The catalyst was successfully recycled for the sample Suzuki-Miyaura reaction nine consecutive times with small drop in catalytic activity.
Highly water-dispersible magnetite nanoparticle supported-palladium-β-cyclodextrin as an efficient catalyst for Suzuki-Miyaura and Sonogashira coupling reactions

We reported here a novel highly water-dispersible and recoverable magnetite supporting a palladium-β-cyclodextrin complex as an efficient catalyst in Suzuki-Miyaura and Sonogashira carbon-carbon coupling reactions. The magnetite nanoparticle supporting catalyst was characterized by FT-IR, CHN, EDS, TGA, XRD, TEM and VSM. The prepared catalyst displayed excellent activity for a wide range of substrates in aqueous solution under mild reaction conditions. The reusability of the magnetite supporting palladium-β-cyclodextrin nanocatalyst was successfully examined five times with a slight loss of catalytic activity.

supporting information; experimental part, p. 9606 - 9615 (2010/10/18)
A straightforward two-step synthesis of trans-3,4-disubstituted succin imides through a palladium-catalyzed Sonogashira reaction and an iron-catalyzed double carbonylation is described. In situ oxidative dehydrogenation gave the corresponding 3,4-diarylmaleimides. By starting from readily available aryl and hetgeroaryl halides, a variety of new analogues and derivatives of bioactive 3,4-bisindolylmaleimides are obtained in good yield and selectivity.
Synthesis and SAR of a mGluR5 allosteric partial antagonist lead: Unexpected modulation of pharmacology with slight structural modifications to a 5-(phenylethynyl)pyrimidine scaffold
Sharma, Sameer,Rodriguez, Alice L.,Conn, P. Jeffrey,Lindsley, Craig W.
scheme or table, p. 4098 - 4101 (2009/05/26)
This Letter describes the synthesis and SAR, developed through an iterative analogue library approach, of a mGluR5 allosteric partial antagonist lead based on a 5-(phenylethynyl)pyrimidine scaffold. With slight structural modifications to the distal pheny
