The bright future of stereoselective synthesis of co-ordination compounds

Transfer of chirality during the build-up of molecules has been applied innumerable times in organic chemistry since the end of the 19th century, when it was introduced in the so-called asymmetric synthesis by E. Fischer. Although analogous reactions were introduced in co-ordination chemistry in its early development, diastereoselective reactions have not been applied in a very systematic way f...

Independence and Co-ordination –

* The views expressed in this paper are personal. Most outsiders tend to base their analysis of the future of the Eurosystem on the shape of the Federal Reserve System in the US. This paper argues that the US model is inappropriate. It suggests that the Eurosystem is pursuing a different arrangement, where the balance of power in the national central banks rather than in the centre may continue...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Co-ordination and Specialisation

This paper addresses the problem of division of labour as an evolutionary process in which co-ordinated agents attempt problem-solving as a search in problem space. Co-ordination stress and learning trigger adaptation but as complexity rises radical solutions are sought prompting radical organisational as well as technological change. The analytical issues involved are further explored by resor...
