Chapter I describes the synthesis of arylolefins in fair to good yield by the cross-coupling reaction of arylmercurials and vinyl halides catalyzed by 10% ClRh(PPh(,3))(,3). The reaction appears to involve initial oxidative addition of the vinyl halide to the rhodium(I) catalyst to yield a vinyl rhodium(III) species and subsequent arylation by the organomercurial to generate an aryl vinyl.

Organomercury compounds are widely used in medicinal applications. Alkoxyalkylmercurials have been used as fungicides and bacteriocides and, in addition, a range of diuretics containing substituted (betap-methoxyethyl)mercury(II) groups RCH(OMe)CH2Hg and CH2(OMe)CH(R)Hg, have been extensively used since the 1920's. Theophylline is often administered in conjunction with the mercurial diuretics.

Organomercury compounds were the sources of electro-generated anions,15 the convenient precursors for prepara-tive synthesis10,16 and the mediators of enantioselective electrosynthesis.17 They assisted in the production of sub-stances the direct synthesis of which was complicated or non-selective.18,19 Organomercury compounds were used as medicinal.

Organocobalt and organomercury compounds have a similarity in reactivity because each contains a carbon-metal bond that is easily cleaved by heating or photolysis. Carbon-centered radicals produced from organomercury compounds undergo hydrogen-atom abstraction and radical addition reactions. Concern about the toxicity of organomercury compounds reduces their usefulness as radical precursors.

The widespread use of organoboron compounds justifies the efforts devoted to their synthesis, as well as toward developing an understanding of their reactivity. The nature of the mono- or diboron species is of paramount importance in determining the reversible covalent binding properties of the boron atom with both nucleophiles and electrophiles. By wedding the rich chemical potential of.

Mercury Mercury is an element and a metal that is found in air, water, and soil. It exists in three forms that have different properties, usage, and toxicity.

After the initial chapters have discussed the synthesis, reactivity, and properties of the compounds in general, each of the next nine chapters takes a specific sulfur containing functional group and expands the discussion on synthetic procedures. The final chapter looks at the major uses of organo-sulfur compounds and their impact on biological and environmental areas. Special offers and.

Introduction Considerable progress has been made in understanding the mechanisms of the antibacterial action of antiseptics and disinfectants (215, 428, 437).By contrast, studies on their modes of action against fungi (426, 436), viruses (298, 307), and protozoa have been rather sparse.Furthermore, little is known about the means whereby these agents inactivate prions ().

Problems associated with the synthesis of almost perfect crystals are studied at the Institute of Crystallography of the Academy of Sciences of the USSR. At the institute, research in such problems was begun in the 1940’s by A. V. Shubnikov and was conducted under his direction for many years. Various areas in crystallography that were developed by Shubnikov’s students are associated with.
