Current Organic Chemistry - Volume 11, Issue 16, 2007

The Number 16, 2007 Organometallic Chemistry, Coordination Chemistry and Catalysis thematic issue of Current Organic Chemistry comprises five review papers having synthesis, reactivity and applications of metal complexes as the unifying theme. Organometallic catalysis, activation of C-H and C-C bonds, cooperation of hydrogen bonds and metals, recognition and selective cleavage of nucleic acids by metal-based systems, Read More

Platinum complexes have played an important role in our understanding the mechanisms of arene and alkane CH activation and developing catalytic methods for hydrocarbon CH functionalization. Knowledge of the factors controlling the reactivity of the metal center acquired over the past few years enabled significant progress in the field. Among the most challenging problems which have to be solved yet are i) the use Read More

This review gives an overview of the early development of transmetallation reactions for synthetic purposes and presents some recent results on the transmetallation reaction as a part of cross-coupling reactions and the mechanism of these reactions.

A major challenge in chemistry is the design of catalysts that can carry out important chemical transformations with the extraordinary efficiency of enzymes. In many cases nature does this by making metals and hydrogen bonding groups to work cooperatively. This review provides a description of recent work inspired by nature where the combination of metal ions and hydrogen bonding groups has been used to enhance the pro Read More

Recent developments in artificial enzymes for site-selective scission of RNA have been reviewed, and their advantages over ribozymes are discussed. Most of previous reports involve covalent fixation of molecular scissors to sequence- recognizing moieties. However, non-covalent strategy, in which these two components are never covalently bound each other, has made remarkable progresses. When oligonucleoti Read More

The luminescence of lanthanide ions makes them interesting for a wide variety of applications and several researchers try to optimize this property. In this paper we give a brief overview of the luminescence process and of the techniques utilized to characterize the photophysical properties. Several recent examples of luminescent complexes with small molecule sensitizers will also be discussed.
