Progress in metathesis chemistry
In contrast to the production of simple bulk chemicals and polymers, which started shortly after the discovery of the “olefin scrambling” reaction, it was not until much later that this transformation was “rediscovered” by the academic world. In the last decade of the 20th century, the so-called olefin metathesis reaction gained real significance in advanced organic synthesis [1]. The developme...
متن کاملProgress in allene chemistry.
During the last three decades the chemistry of allenes has fascinated scientists worldwide. Thus, its beauty has been recognized in a diversity of allenic natural products, many of them showing interesting or promising therapeutic activities. In fact, around 150 natural products containing an allenic or cumulenic structure have been identified. In the meantime, the reactivity of allenes has bee...
متن کاملProgress in Polyarsolyl Chemistry
The synthesis of heteroatom analogues of the cyclopentadienyl anion Cp- is a fascinating and challenging field of research. The replacement of methine moieties by phosphorus is well investigated for the synthesis of mono-, tri- and pentaphospholyl ligands. On the other hand, arsenic derivatives are rare and 1,2,4-triarsolyl and tetraarsolyl salts are unknown. Herein, we report on the synthesis ...
متن کاملProgress in liquid crystal chemistry
Since their discovery in 1888 by the botanist Friedrich Reinitzer, who studied the melting behavior of cholesteryl benzoates, liquid crystals have developed from a mere curiosity to a highly interdisciplinary research field, with LC displays being the most important application to date [1,2]. However, besides the use of thermotropic liquid crystals for display technology many other applications...
متن کاملProgress in metathesis chemistry II
Five years have passed since the first publication of the Thematic Series on Olefin Metathesis in the Beilstein Journal of Organic Chemistry [1]. During these years the research continued to progress at full speed. Astute readers of this Thematic Series, as well as readers of the recent books devoted to olefin metathesis [2,3], can easily see that a great number of studies in this field have ad...
