Current Organic Chemistry - Volume 11, Issue 1, 2007

After the success of the 1st Organophosphorus (OP) special issue of Current Organic Chemistry consisting of two parts published back to back it is my pleasure to announce the 2nd. OP special issue approved by the Editor-in-Chief, Professor Attaur- Rahman and the management of Bentham. The first three papers cover relatively large molecules, such as phosphorus-containing cyclodextrins, calixarenes and cyclophanes, as w Read More

Basic synthetic procedures commonly applied for the preparation of racemic and optically active phosphinic and phosphinous acid derivatives containing a t-butyl group as a single bulky substituent are presented. Mechanistic and stereochemical aspects of the presented protocols are discussed. Structural studies, which include the X-ray and vibrational circular dichroism-based determinations of the absolute configurati Read More

Crowded triarylphosphines have attracted broad interest for a long time since they have unique structure, properties, and reactivity. This review article focuses on synthesis, structure, properties, and application of crowded triarylphosphines represented by trimesitylphosphine and tris(2,4,6-triisopropylphenyl)phosphine, which are of interest from contemporary viewpoint of material science rather than ligands for transition m Read More

Azaphospholes are 6π aromatic heterocycles incorporating at least one σ2, λ3-phosphorus atom and one σ3, λ3- nitrogen atom. This review covers the synthesis, structural characterization, reactions and theoretical calculations of azaphospholes anellated to a six - or five-membered heterocyclic ring, reported during the last 10-12 years. Three synthetic methods, namely [4+1] cyclocondensation, [3+2] cyclocondensation and 1,5- Read More

The use of several zirconium reagents as the Schwartz reagent [Cp2ZrHCl]n, the dimethylzirconocene Cp2ZrMe2, the zirconocene [Cp2Zr], and the diphenylzirconocene Cp2ZrPh2 allows the synthesis of a variety of new linear and cyclic P-C and P-N ligands. 1,1 diphosphines can be prepared from unsaturated monophosphines. A useful methodology involving ring opening reactions permits the preparation of phosphinite-phosp Read More

The synthesis of chiral heterocyclic phosphines, such as phosphiranes, phosphetanes, phospholes and phosphinanes will be reviewed. These compounds play a pivotal role as ligands and organocatalysts, respectively, in asymmetric reactions. Synthetic approaches will be analyzed in the framework of several sub-categories e.g. the preparation of mono-, bis- and poly(phosphines). General synthetic strategies for the prep Read More

The search for suitable ionic liquids that are non-volatile, non-toxic, dissolve a variety of reactants and are recyclable is a real challenge for chemists to be able to replace the traditional solvents that are volatile, flammable and toxic. This segment of chemistry has, these days, become a firm part of green chemistry attracting much attention. The present review summarizes and critically discusses the data accumulated in Read More
