A Zn(II) coordination complex was synthesized, characterized, and used for catalytic aquathermolysis of heavy oil at low temperatures for the first time. The effects of water content and catalyst concentration on aquathermolysis were investigated. And then a tri-component coupling aquathermolysis of waterheavy oil-methanol was designed and the reaction conditions were investigated. With the catalyst and methanol, the reaction occurred at temperatures as low as 180°C. The viscosity of the product was also substantially reduced from around 24 400 to 6420 mPa s by the decomposition of the large hydrocarbon molecules.

A series of cis-dioxomolybdenum(VI) complexes of general formula cis-[MoO2(HLn)] (1-4) have been synthesized in 80-85% yields by reacting equimolar amounts of [MoO2(acac)2] (acac- = acetylacetonate) with 2,2′-(2-hydroxy-3,5-R1,R2-benzylazanediyl)diethanols (H3Ln, n = 1-4) in methanol. Characterization of the complexes has been performed by elemental analysis, spectroscopic (IR, UV-Vis, 1H and 13C NMR) and electrochemical measurements. The molecular structures of all four complexes have been determined by single-crystal X-ray diffraction studies. In each of these analogous complexes, the metal centre is in a distorted octahedral NO5 coordination sphere assembled by the single edge shared 5,5,6-membered chelate rings forming NO3-donor (HLn)2- and two cis oriented oxo groups. Crystal structures of the complexes reveal formation of discrete centrosymmetric dimeric species via a pair of reciprocal intermolecular O-HO hydrogen bonding interactions. Spectroscopic data of all the complexes are consistent with their molecular structures. In the cyclic voltammograms, the redox-active complexes display a quasi-reversible to irreversible metal centred reduction with the cathodic peak potential in the range -0.92 to -1.12 V (versus Ag/AgCl). All the complexes have been evaluated for their catalytic activities in oxidative bromination reactions of styrene and salicylaldehyde and in benzoin oxidation reaction.
Reaction on a solid surface - A simple, economical, and efficient Mannich reaction of azacrown ethers over graphite

, p. 426 - 434 (2008/09/20)
Graphite brings about a rapid Mannich reaction with a range of activated and unactivated phenolic compounds such as p-cresol and p-nitrophenol. The reactions are carried out with azacrown ether and paraformaldehyde in solvent-free conditions at 100 °C for 20-30 min. The graphite powder can be reused up to three times after simple washing with acetone.
