Current Organic Chemistry - Volume 14, Issue 12, 2010

These days the organophosphorus discipline is in focus within organic chemistry. After the success of Organophosphorus (OP) special issues 1-7 of Current Organic Chemistry, the 8th OP special issue is announced here showing up mainly green and synthetic aspects. Two articles illustrate the advantages of applying ionic liquids instead of traditional solvents. In the first of these, efficient organophosphorus syntheses that were Read More

The application of 'green' solvents such as ionic liquids and water is currently being vigorously pursued because of attractive features such as the acceleration of a variety of reactions, their non-toxic nature, the possibility of dissolving a variety of reactants and recyclability in the case of ionic liquids, and cheapness in the case of water. The present review summarizes and critically discusses the data accumulated in recent year Read More

This review deals with the application of ionic liquids in the activation of small molecules such as dihydrogen, carbon monoxide and carbon dioxide in various homogeneous catalytic reactions. The catalysts were restricted to transition metal catalysts containing phosphorus ligands (mainly phosphines).

Alkenylphosphines are compounds of great interest in view of their structures. The most interesting feature is the carbon-carbon double bond, which is directly linked to the phosphorus atom. Nucleophilic addition or cycloaddition reactions can take place at this unsaturation, which can also be used as a coordinating part in the presence of a metal. Thus, alkenylphosphines have found numerous applications in various fields o Read More

In the present review we attempt to systematize and generalize the available data on prototropy in imidoylphosphonates containing α-hydrogen atoms in the N- or C-alkyl groups of the C=N bond. Prototropic transitions in C=N-CH triad of imidoylphosphonates leading to biorelevant α-aminophosphonates are in main focus of the review. Central to this endeavour is elucidation of the effect that the phosphoryl or phosph Read More

Heteroaromatics-containing polymers comprise a huge class of materials that have received considerable attention due to their interesting electrical, electrochemical and optical properties. In this review, the recent advances on the use of cross-coupling reactions for the synthesis of heteroaromatic, conjugated monomers and polymers for the optoelectronic interests and applications are summarized. This review arti Read More

The concept of π-acid catalysis has emerged as a powerful principle for the chemists to create diversity and originality from simple molecules. Carbophilic late transition metals such as gold or platinum have appeared as fascinating catalysts able to activate alkenes, alkynes and other unsaturated derivatives towards anti nucleophilic addition via complexation on a single empty coordination site. Tunable chiral square-pl Read More

The intermolecular radical addition to the carbon atom of imine derivatives has received much less attention until recently, although the use of radical reaction in organic synthesis has continued to increase. This review highlights the intermolecular carbon-carbon bond forming reactions based on carbon radical addition to the carbon-nitrogen double bond. Particularly, the radical reactions of oxime ethers, hydrazones, sul Read More
