The Synthesis of Organic Compounds

The silver fluorocomplexes, ie, silver hexafluoroantimonate [26042-64-8], AgSbF silver hexafluorophosphate [26042-63-7], AgPF silver tetrafluoroborate [14104-20-2], AgBF and other salts such as silver trifluoromethane sulfonate [2923-28-6], CF SO Ag, and silver trifluoroacetate [2966-50-9], CF COOAg, play an important role in the synthesis of organic compounds and have gained potential industrial importance.

The Diels-Alder reaction, in which two alkenes combine to give a new product, is one of the most frequently used reactions for the synthesis of organic compounds. Thousands of examples are found in the chemical literature. The reaction of butadiene is a simple example. 

The single-bond compounds between Si, Ge, and Sn and chalcogens (S, Se, Te) are reactive and used as synthetic intermediates in the synthesis of organic compounds, organochalcogen compounds, organo-silicon, -germanium and -tin compounds, and transition metal-chalcogen complexes and clusters. 

The traditional way of producing derivatives for analytical purposes aims at preserving, as much as possible, the important structural features of the analyte. In the case of organotin compounds this means that the tin moieties of the compound should appear in the derivative, as occurs in the methods described in Section V.A. Nevertheless, many organotin compounds are important intermediates in the synthesis of organic compounds devoid of metallic atoms. Such procedures can afford good derivatizing schemes, as described in Section V.B. 

Cyclopropane, C3H6, is used in the synthesis of organic compounds and as a fast-acting anesthetic. It undergoes rearrangement to form propene. If cyclopropane disappears at a rate of 0.25 mol/s, at what rate is propene being produced ...

Free radicals are highly reactive species and react with the CH3CI and CH3CH3 products to produce more free radicals, which, in turn, form even more products. And so it goes on until you end up with a reaction mixture containing lots of different compounds. Each of these compounds will be produced in low yields and will be difficult to isolate. It is for these reasons that reactions involving homolytic fission are unsuitable in the synthesis of organic compounds. 

Reactions that proceed via heterolytic fission tend to produce far fewer products than those involving homolytic fission and, as a result, are far better suited in the synthesis of organic compounds. 

Volume 69 of Advances in Heterocyclic Chemistry consists of six contributions. The opening chapter, by Professor R. M. Moriarty and Dr. O. M. Prakash of the University of Illinois at Chicago, summarizes the use of organohypervalent iodine reagents in the synthesis of organic compounds, a subject of increasing importance and one for which no general review has as yet appeared. 

One of the simplest examples for such effects is the oxidation of ammonia with iron oxide-bismuth oxide as a catalyst. Here, the addition of bismuth oxide results in the formation of nitrous oxides as the main product whereas an iron oxide catalyst without bismuth oxide yields nitrogen almost exlcusively. Selectively guiding catalysts become increasingly important in the synthesis of organic compounds, e.g., in the hydrogenation of carbon monoxide where the type of obtainable product can be varied, within wide limits, by the kinds of catalysts and promoters which are employed. 

One of the most interesting aspects of organic chemistry is that of dealing with the building-up of complex substances from simpler ones. The synthesis of organic compounds, whether for scientific or industrial purposes, has been very important in the development of the science and is still of great importance today. ... 

Ices formed as mantles on silicate grains in interstellar space, trapping noble gases and providing sites for the synthesis of organic compounds. As the solar system formed, these ices were vaporized, particularly in the warmer regions near the Sun. Water ice recondensed outside the snowline and combined with rocky material and surviving interstellar material to form planetesimals. 

The energy from the decay of radioactive elements was probably not an important energy source for the synthesis of organic compounds on the primitive earth since most of the ionization would have taken place in silicate rocks rather than in the reducing atmosphere. The shock wave energy from the impact of meteorites on the earth s atmosphere and sur-... 

The synthesis of organic compounds on the preparative scale has been achieved, only very recently. Typical conditions are low power levels in the glow or corona discharge and fast flow rates for the organic material. Fig. 1... 

A floodgate was opened. Chemists suddenly found a whole new field of research available to them the synthesis of organic compounds found in living organisms and, even more important, other compounds similar to those found in plants and animals but not actually found in the natural world. 

In particular, water treatment in principle constitutes one of the most important fields of application of the photocatalytic processes that involve both degradation reactions for the removal of environmental pollutants and selective reactions for the synthesis of organic compounds. 

Palladium-catalyzed reactions and cross-couplings are vital and widely used methods in the synthesis of organic compounds. Many examples have emerged utilizing pyran-2-ones and coumarins in palladium- and nickel-mediated reactions, and several of these are presented in this section.
