Hydrotalcite-quinolinate composites as catalysts in a coupling reaction

Samples of layered double hydroxides were prepared by a sol-gel procedure. Quinolinate Al(C9H6NO)3 units were added during the synthesis, leading to composite quinolinate hydrotalcite-like compounds. The amount of quinolinate was varied, showing that the number of organic building blocks determines the physicochemical properties of materials, which differ significantly from those commonly repor...

Artificial Catalysed Reaction Networks for Search

There is a tension between biology’s emphasis on perpetuation and the change required by biologically-inspired evolutionary algorithms. But there were radical changes when life first emerged from a prebiotic soup of chemicals. We investigate the possibility of taking ideas about the origin of life to develop a novel general purpose constructive search technique, inspired by ideas from autocatal...

A simplified green approach for synthesis of arylquinoxalines under solvent-free clay-catalysed conditions

A friendly benign, green, rapid and facile strategy for synthesis a series of arylquinoxalines was achieved by condensation of aromatic 1,2-diamines with arylglyoxals under clay-catalyzed as an inexpensive and eco-friendly catalyst using grindstone chemistry. Significant decreases in reaction times and high yields have been observed by this green chemistry approach in comparison with previously...

Transesterification Of Sunflower Oil Using Mg-Al- Co3 Hydrotalcite As A Catalyst

An efficient and facile synthesis of fatty acid methyl esters (FAMEs) using sunflower oil and methanol has been carried out in the presence of a solid base Mg-Al-CO3 hydrotalcite heterogeneous catalyst. This protocol promotes the environment friendly conditions as the hydrotalcites are non toxic, recyclable, takes less reaction time and is easy to work up. The hydrotalcite showed high activity ...

Protease-catalysed Direct Asymmetric Mannich Reaction in Organic Solvent

We reported the first enzyme-catalysed, direct, three-component asymmetric Mannich reaction using protease type XIV from Streptomyces griseus (SGP) in acetonitrile. Yields of up to 92% with enantioselectivities of up to 88% e.e. and diastereoselectivities of up to 92:8 (syn:anti) were achieved under the optimised conditions. This enzyme's catalytic promiscuity expands the application of this bi...
