For the first time we have been able to employ enantiopure 1,2-amino alcohols derived from abundant amino acids in C−C bond-forming hydrogen-borrowing alkylation reactions. These reactions are facilitated by use of aryl ketone Ph*COMe. Racemisation amine stereocentre during can be prevented sub-stoichiometric base and protection nitrogen with a sterically hindered triphenylmethane (trityl) or b...

Among the various film preparation methods, electroplating is one of simplest and most economical methods. However, it challenging to collect a dense single Pd through plating, owing accumulation stress in during process. Therefore, characteristics plated have not been clearly identified, although pure widely used metallic-hydrogen-purification membranes. In this study, concentration was reduce...

Because of the relative simplicity of ita substrate, hydrogen, the enzyme hydrogenase is of particular interest in the study of the mechanism of enzyme catalysis. In its reaction with molecular hydrogen, hydrogenase simulates, in certain respects, the action of active platinum catalysts. It catalyzes the reduction by hydrogen of a variety of dyes and of various organic and inorganic compounds, ...

A palladium composite membrane was prepared via electroless plating technique using organic-inorganic method during activation process. The ceramic support surface was modified by two TiO2-boehmite and one γ-alumina layers to avoid Pd penetration in support pores. Thin and defect-free Pd composite membrane was obtained by creating a relative smoothness on the ceramic support and using Pd nanopa...
