Two coordination complexes of Cu(II) and Co(II) involving 3,5-dimethylpyrazole viz. { [Cu(mu-O,O’-SO4) (Hdmpz)(2)(H2O)]center dot 2H(2)O}(n) (1) and [Co(Hdmpz)(4)(H2O)(2)Cl-2 (2) (where Hdmpz = 3,5-dimethylpyrazole) have been synthesized in purely aqueous medium at room temperature. Crystal structure of complex 1 consists of a polymeric chain of distorted square pyramidal Cu(II) centers bridged by bidentate sulfato ligands. The polymeric chain in 1 has been stabilized by N-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions. Particularly relevant is the polymeric chain in 1, since in addition to the afore mentioned non-covalent contacts, unprecedented chalcogen bonding interactions involving the sigma-hole at the tetrahedral sulfur atom are observed and characterized using theoretical calculations. To our knowledge, sigma-hole chalcogen bonding interactions involving tetrahedral sulfur atom have not been previously reported in the literature. The lattice water molecules self assembles the polymeric chains of 1 into a 3D supramolecular architecture via C-H center dot center dot center dot O hydrogen bonding interactions. The cationic units in the crystal structure of 2 self assembles via O-H center dot center dot center dot Cl, N-H center dot center dot center dot Cl and C-H center dot center dot center dot Cl weak hydrogen bonding interactions into a 2D supramolecular architecture induced by chloride anions in the lattice. PXRD patterns of 1 and 2 demonstrate good phase purity of the complexes. In addition, the thermal behaviour of the complexes has also been investigated.

The limitations of arene C-H functionalization of aryl sulfonamides containing strongly coordinating Nheterocycles were overcome using a Rh(III) catalyst. The site-selectivity of C-H carbenoid functionalization at the ortho position relative to either the sulfonamide or N-heterocycle directing groups was elegantly switched using solvents of different polarities and different additive concentrations. Importantly, sulfonamide-group-directed ortho-C-H carbenoid functionalization tolerated strongly coordinating N-heterocycles, including pyridine, pyrrole, thiazole, pyrimidine, and pyrazine. Density functional theory (DFT) calculations were performed to rationalize the reaction mechanisms and the influence of reaction polarity.

Pyrazoles and hydrazones, as two significant kinds of potentially bioactive compounds, were produced with good to excellent yields by condensation of beta-dicarbonyl compounds with hydrazines in aqueous media in the presence of Fe3O4@CeO2 nanocomposite as an efficient heterogeneous nanocatalyst. The magnetic nanocatalyst can readily be separated using an external magnet and reused at least six times without significant loss in activity. The products were characterized by IR and H-1 and(13)C NMR spectra.

Two novel space craft-like octanuclear Co(II)-silsesquioxane nanocages, {Co-8[(MeSiO2)(4)](2)(dmpz)(8)} (SD/Co8a) and {Co-8[(PhSiO2)(4)](2)(dmpz)(8)} (SD/Co8b) (SD = SunDi; Hdmpz = 3,5-dimethylpyrazole), have been constructed from two similar multidentate silsesquioxane ligands assisted with a pyrazole ligand. The Cob skeleton consists of eight tetrahedral Co(II) ions arranged in a ring and is further capped by two (MeSiO2)(4) ligands up and down. The auxiliary dmpz(-) ligands seal the ring finally. Electrospray ionization mass spectrometry revealed SD/Co8a and SD/Co8b are highly stable in CH2Cl2. Magnetic analysis implies that SD/Co8a announces antiferromagnetic interactions between Co(II) ions. Moreover, both of them display good homogeneous catalytic activity for hydroboration of ketones in the presence of pinacolborane under mild conditions.

The complex [MoO(O-2)(2)(pyrazole)(2)] (1) is an effective catalyst for the oxidation of organic sulfides (methyl-phenylsulfide and diphenylsulfide). Reactions can be run in water as the only medium, at low temperature (25 degrees C), with low catalyst loadings (0.2 mol%) and excellent H2O2 efficiency with no significant non-productive decomposition of the oxidant. Under conditions that favor sulfone formation, the overall process, including isolation of the precipitated product (by filtration or centrifugation) and recycling of the aqueous phase con-taining the catalyst, can be performed in the absence of organic or ionic liquid solvents. Catalytic results with the recycled aqueous phase were the same as those obtained in the first cycle. With water as the sole solvent, 1 is a superior catalyst to the 3,5-dimethylpyrazole complexes [MoO(O-2)(2)(dmpz)(2)] (2) and [Hdmpz](4)[Mo8O25.8(O-2)(0.2)(dmpz)(2)]center dot 4H(2)O (3). Crystal structures for 1 and 3 are presented.

The synthesis of new cationic macrocyclic host molecules is described. These macrocycles are comprised of glycoluril oligomers linked to two pyrazolium groups, which form part of a cationic wall facing into their cavities. A number of derivatives have been prepared with an objective to increasing the cavity size, and each new product has been fully characterized. Preliminary investigations of pK(a)s of Me(10)Tu-[3](2+) and an interaction of L-glutamine indicate a potential for binding anionic molecules that also carry H-bond donor groups.
