palladium is the best metal catalyst for suzuki cross coupling reaction for synthesize of unsymmetrical biaryl compounds. but its high cost limits its application in wide scale. using of nanoscale particles as active catalytic cites is a good approach for reducing needed noble metal. by loading precious nanoparticles on magnetic nanocores as a support, recycling and reusing of catalyst will be ...

We provide facile synthetic methods of 1,1′-diaryl-4,4′-bibenzo[ c ]thiophene derivatives by Stille or Suzuki coupling reaction.

where Σ is a smooth bounded domain in R, has been extensively studied by many authors. Let (uk, ρk) be a unbounded sequence of solutions to (1.2) with ρk ≤ C,maxx∈Σ uk(x) → +∞. Then it has been proved that (P1) (no boundary bubbles) uk is uniformly bounded near a neighborhood of ∂Σ (Nagasaki-Suzuki [33], Ma-Wei [29]); (P2) (bubbles are simple) ρk → 8mπ for some m ≥ 1 and uk(x) → 8π ∑m j=1 G(·, ...

Palladium catalyzed cross-coupling reactions of 2-iodoimidazole have been studied to synthesize imidazole-containing protein farnesyltransferase inhibitors. The Suzuki coupling reaction proved to be very efficient to introduce functionalized alkyl chains at the 2-position of the imidazole ring and a new synthesis of the required alkenylboronates was realised by a reaction of cross metathesis. A...

Box 53909, Jeddah 21593, Saudi Arabia Full list of author information is available at the end of the article Abstract Using the concept of u-distance, we prove a fixed point theorem for multivalued contractive maps. We also establish a multivalued version of the Caris...

In the first part of this paper, we prove the existence of common fixed points for a commuting pair consisting of a single-valued and a multivalued mapping both satisfying the Suzuki condition in a uniformly convex Banach space. In this way, we generalize the result of Dhompongsa et al. 2006 . In the second part of this paper, we prove a fixed point theorem for upper semicontinuous mappings sat...

The harvestmen genus Cladolasma Suzuki, 1963, previously known only from Japan and Thailand, is here reported from China for the first time. A new species, Cladolasma damingshan sp. nov., is described on the basis of a single male specimen collected from Daming Mountain, Guangxi, China. The new species is distinct from C. parvulum Suzuki, 1963 and C. angka (Schwendinger & Gruber, 1992) in lacki...

A variety of triazole-based monophosphines (ClickPhos) have been prepared via efficient 1,3-dipolar cycloaddition of readily available azides and acetylenes. Their palladium complexes provided excellent yields in the amination reactions and Suzuki-Miyaura coupling reactions of unactivated aryl chlorides. Ligand 7i, which has a 2,6-dimethoxybenzene moiety, provided good results in Suzuki-Miyaura...

In this paper, we proposed a novel method for evaluating intonation of an English utterance spoken by a learner for intonation learning by a CALL system. The proposed method is based on an intonation evaluation method proposed by Suzuki et al., which uses “word importance factors,” which are calculated based on word clusters given by a decision tree. We extended Suzuki s method so that multiple...
