A polyaniline-anchored palladium heterogeneous catalyst was prepared and screened for coupling reactions of aryl halides. The robust, recyclable catalyst was effective in Mizoroki–Heck and Suzuki–Miyaura reactions of aryl bromides and iodides. The catalyst system was further employed for one-pot Wittig–Heck and Wittig–Suzuki combinations to obtain conjugated compounds in good conversions.

Tetra-n-butylammonium salts of [M₄(PW₉O₃₄)₂]^m− and [M₄(P₂W₁₅O₅₆)₂]ⁿ⁻ were used as effective catalysts for the oxidation of cyclooctene and cyclohexene under various conditions. Wells–Dawson-type polyoxometalates were less active than Keggin ones. Higher conversions were obtained with Zn- and slightly lower with Fe-substituted polyoxometalates of both sandwich-type compounds.

A metal–organic framework material, MIL-125(Ti), was solvothermally prepared and characterized, and was then used as an adsorbent for Rhodamine B removal in aqueous solution.

Neutral binuclear and mononuclear ruthenium complexes with bis(nicotinate)- or bis(isonicotinate)-polyethylene glycol esters and ethylene glycol monomethyl ether nicotinate, respectively, were synthesized and characterized. Stability of the binuclear complexes in the presence of DMSO was studied, as well as the formation of a cationic complex. Ligand precursors and ruthenium(II) complexes were tested for their in vitro cytotoxicity against five tumour cell lines.

A simple and green synthesis of palladium nanoparticles, using the aqueous extract of herbal tea (Stachys lavandulifolia) has been described. Moreover, the Pd-NPs stabilized by S. lavandulifolia extract were applied in the Suzuki cross-coupling reactions in water at mild conditions.

Palladium nanoparticles supported on cucurbit[6]uril are an efficient and recyclable catalyst for Suzuki reactions of various aryl halides with arylboronic acids under mild conditions. These reactions were carried out in EtOH–H₂O mixture in the presence of 0.05 mol% Pd(0).

A heterogeneous Pd(II) salen complex anchored to multi-walled carbon nanotubes (Pd-Salen@MWCNTs) was used as a catalyst for Heck and Hiyama couplings.

CTH reaction of differently substituted aldehydes and ketones were studied using iron phthalocyanine catalyst, in order to alternate the typically used rare transition metals (Ir, Rh, Ru) by easily available and less expensive metal. During this study iron phthalocyanine was proven to be an efficient hydrogenation catalyst and the anchored version of it was also prepared. The immobilized iron phthalocyanine showed similar activity in CTH reaction of carbonyl compounds and it was easy to handle and possible to recycle.

An efficient tandem route for the synthesis of polyfluoroterphenyl derivatives has been developed using Pd-catalyzed three-component coupling reaction involving direct CH activation of perfluoroarenes.
