Asymmetric oxidation of aryl methyl sulfides was catalyzed by Ti(OiPr)₄–Schiff base (L³–L⁵) systems with H₂O₂ as terminal oxidant, giving corresponding chiral sulfoxides up to 73% ee and 89% yield with 0.5–1.0 mol% catalyst loading.

SmNiCl₂ as a reductive system promoted reductive coupling of aryl adehydes and aryl ketone into pinacols in good yields and also promoted coupling reaction of aryl sulfonyl chlorides and active halides into sulfones in good yields.

The Mannich reaction is a valuable coupling protocol for preparing amino carbonyl compounds. Chemistry has made significant advances in this field, but some challenges remain. Recently developed methods for carrying out this reaction in water as a reaction media are reviewed, and viewed from the perspective of green chemistry.

A series of N²,N^2′-disubstituted oxalic acid bishydrazides were been synthesized and applied to be novel and effective ligands for copper-catalyzed Ullmann- type CN coupling reaction in water. A variety of amines could be effectively N-arylated with aryl halides under both microwave irradiation and conventional heating (even at 30 °C) with good to excellent yields.

Binding constant of complexes with DNA reveals intercalation mode of interaction. Geometric change at metal center is responsible for SOD mimic behavior.

Substitution of a chromogenic ligand in triorganotin compounds by anions leads to strong color change and can be used for determination of equilibrium constants for anion exchange and addition reactions and for colorimetric anion sensing in polar organic solvents with selectivity AcO⁻ > F⁻ > H₂PO₄⁻ > Cl⁻ ≫ Br⁻.

An efficient catalyst system, containing benzimidazolium salts bearing trimethylsilyl moieties in Suzuki–Miyaura reaction of aryl halides with phenylboronic acid under microwave irradiation, and antimicrobial activities of the benzimidazolium salts are reported.

New chelating bis-N-heterocyclic carbene ligands have been synthesised; their coordination chemistry and catalytic applications with iridium and rhodium have been investigated.

The synthesis, characterization, surface activity and hydrolysis-resistant ability of a new type of ethoxylated double-tail trisiloxane surfactants containing a propanetrioxy spacer are described. The trisiloxane surfactant 1P possesses a good spreading ability on parafilm and Ficus microcarpa leaf surfaces, and its aqueous solutions are stable for 130 days in an acidic environment (pH 4.0) with surface tension values less than 23 mN m⁻¹.

Two new boron complexes were synthesized from N-[3-(methylmercapto)aniline]-3,5-di-tert-butylsalicylaldimine (LH) with boron reagent BPh₃ or BF₃.Et₂O. All new boron complexes were fully characterized by both analytical and spectroscopic methods. The catalytic activites of complexes [LBPh₂], 2, and [LBF₂], 3, in the transfer hydrogenation of acetophenone derivatives were tested. The stable boron complexes were found to be efficient catalysts in the transfer hydrogenation of aromatic ketones in good conversions up to 99% in the presence of iso-PrOH/NaOH.

A reusable CuSO₄·5H₂O/cationic 2,2′-bipyridyl system catalyzed the homocoupling reaction of terminal alkynes in water using I₂ as the additive in the presence or absence of TBAB, giving the 1,3-diynes in good to high yields. After reaction, the residual aqueous solution could be reused several times.

The use of functionalized polyethylene glycol resulted in an improvement of the regioselectivity, with the β-adduct being the major product. Furthermore, different silanes as hydride sources also exerted some influence on the regioselectivity.
