The reaction of arylsulfonyl chlorides with acrylate esters in the presence of a catalytic amount of PdCl2(PhCN)2 under solid-liquid phase transfer conditions gives the corresponding 3-aryl-2-propenoates in good yields.

The newly prepared carbene precursor 1,3-dimesitylacenaphtho[1,2-d] imidazolinium chloride, (NHC-H)Cl, 3, could be readily converted into the NHC-silver(I) complex, 4, which is an efficient carbene transfer agent and has been used to synthesise thione 5, trans-[PdCl2(NHC)2], 6 and [RhCl(NHC)(COD)], 7. All compounds synthesised were characterised by elemental analysis, NMR spectroscopy and the molecular structures of the thione 5 and complex 7 were determined by X-ray crystallography. Complex 7 was converted into cis-[RhCl(NHC)(CO)2] and the electron donating properties and trans influence of the NHC ligand were compared with nonanullated counterparts. The catalytic activity in the Heck reaction of 6 and the in situ formed palladium complex was evaluated. The activity of the in situ formed complexes for the Heck coupling of alkenes was high.

, p. 732 - 744 (2018)
Abstract: Synthesis and characterization of new magnetically recoverable and high-performance nanocatalysts of Pd and Pt Schiff base complexes on magnetite nanoparticles were considered. Catalytic activity of these nanocatalysts was explored in Suzuki and Heck cross coupling reactions. The catalysts can be easily reused fourth consecutive runs without significant loss of catalytic efficiency.

Tetrabutylammonium nitrate is reported as an effective reusable medium, suitable reducing and stabilizing agent for the Heck coupling reaction of aryl iodides and bromides with styrene and n-butyl acrylate. The efficient phosphine-free, palladium-catalyzed homocoupling reaction of aryl iodides and bromides is also demonstrated in the presence of tetrabutylammonium nitrate. The ionic liquid, still containing Pd (0) complex, is easily recovered and reused in several runs without losing its efficiency.

In this study, palladium-encapsulated poly(amic acid) (Pd@PAA) nanofibers were prepared by electrospinning, followed by thermal imidization to synthesize palladium-encapsulated polyimide (Pd@PI) nanofibers. Scanning electron microscopy (SEM) images confirmed the preparation of uniform and smooth Pd@PAA and Pd@PI nanofibers. Thermogravimetric analysis (TGA) results reveal that the Pd@PI nanofibers possessed excellent thermal stability. The dispersion of palladium nanoparticles in the polyimide nanofibers was characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The catalysis results show that this Pd@PI fibrous catalyst was very efficient to catalyze the cross-coupling reactions of aromatic iodides with n-butyl acrylate (Heck reaction) or phenylboronic acid derivatives (Suzuki reaction) to afford the desired products in good to excellent yields. Moreover, the Pd@PI catalyst could be easily separated and recovered from the reaction mixture by simple filtration due to the regular fibrous structure and reused for 10 times for both Heck and Suzuki reactions without obvious loss of its initial catalytic activity. Thus, the Pd@PI nanofiber catalyst holds great potential in chemical industry in terms of its excellent catalytic activity and stability.
