On the other hand, asymmetric addition of lithium acetylide in the presence of the ephedrine derivative 46 is a homogeneous reaction and reveals great detail about the reaction mechanism. [Pg.34]

we will discuss the reaction mechanism of the asymmetric lithium acetylide addition to pMB protected amino ketone 41. Then we will discuss some speculation about the asymmetric addition via the novel zinc acetylide addition. [Pg.34]


Although Gibbs published his monumental treatise on heterogeneous equilibrium in 187S, his work was not generally appreciated until the turn of the century, and it was not until many years later that the field of surface chemistry developed to the point that experimental applications of the Gibbs equation became important. [Pg.79]

ChemSketch is a professional software package that is available free of charge from Advanced Chemistry Development Inc. (ACD). Besides the editor, it has several modules (ACD/Dictionary, ACD/Tautomers), extensions, and add-ins concerning the calculation of physicochemical properties, input of spectra and chromatograms, naming of molecules, and a viewer. [Pg.141]

To ensure that eompiilational chemistry develops in an orderly way, researchers muSt provide certain information so that others can reproduce and analyze their results, fiiind et al. proposed... [Pg.7]

With the extensive knowledge available in oil chemistry, development of designer fats and oils is possible (34). This is of special interest to nutritionists who see the possibiUties for stmcturaHy designed fats to meet developing knowledge in clinical nutrition and food product development. [Pg.118]

The above are the opening words of Exodus, the second book of the Petateuch. Already in ancient times, names were important in association with events. As organic chemistry developed during the 20th century, researchers started associating synthetically useful reactions Vi/ith the names of discoverers or developers of these reactions. In many cases such names serve merely as a mnemonic, to remember a reaction more easily there are few chemistry undergraduates who do not know what the Friedel-Crafts reaction is. [Pg.459]

As organic chemistry developed, it became apparent that some systematic way of naming compounds was needed. About 70 years ago, the International Union of Pure and Applied Chemistry (IUPAC) devised a system that could be used for all organic compounds. To illustrate this system, we will show how it works with alkanes. [Pg.582]

Mori et al. have demonstrated the most dramatic uses of lithiated epoxides in natural product synthesis [62]. By employing the chemistry developed by Jackson, and subsequently performing a Lewis acid-catalyzed (BF3 OEt2) cyclisation, tetra-hydrofuran, tetrahydropyran, and oxepane rings are readily accessed this strategy is demonstrated by the synthesis of the marine epoxy lipid 173 (Scheme 5.40) [63]. [Pg.165]

The formation of 27a-27e, 28, and 29 makes use of a chemistry developed by Akiba and coworkers in the 1990s for the synthesis and applications of cyclic lO-P-5 phosphoranes made of two Martin ligands. Methyl, benzyl and phenylth-... [Pg.10]

Investigation of direct conversion of methane to transportation fiiels has been an ongoing effort at PETC for over 10 years. One of our current areas of research is the conversion of methane to methanol, under mild conditions, using li t, water, and a semiconductor photocatalyst. Research in our laboratory is directed toward ad ting the chemistry developed for photolysis of water to that of methane conversion. The reaction sequence of interest uses visible light, a doped tungsten oxide photocatalyst and an electron transfer molecule to produce a hydroxyl i cal. Hydroxyl t cal can then react with a methane molecule to produce a methyl radical. In the preferred reaction pathway, the methyl radical then reacts with an additional wata- molecule to produce methanol and hydrogen. [Pg.407]
