Chemical reactions synthesis

In sections 4.2 and 4.3, you have examined five different types of chemical reactions synthesis, decomposition, combustion, single displacement, and double displacement. Equipped with this knowledge, you can examine a set of reactants and predict what type of reaction will occur and what products will be formed. The Concept Organizer above provides a summary of the types of chemical reactions. 

Chemists classify reactions in different ways. One way is to distinguish among five types of chemical reactions synthesis, combustion, decomposition, single-replacement, and double-replacement reactions. Some reactions fit equally well into more than one of these classes. 

Photolysis. Chemical reaction (synthesis or degradation) induced by absorption of ultraviolet or visible radiation.

The main difference with other optimization techniques [2, 3, 4, 5] is that no external parameters are taken into account to evaluate the results, while other algorithms introduce additional parameters (kinetic/potential energies, mass conservation, thermodynamic characteristics, etc.), this is a very straight forward methodology that takes the characteristics of the chemical reactions (synthesis, decomposition, substitution and double-substitution) to find for optimal solution. 

Organocopper compounds in organometallic chemistry contain a carbon-to-copper chemical bond. Organocopper chemistry is the science of organocopper compounds, describing their chemical reaction, synthesis, and physicochemical properties.

This is the domain of synthesis design, and the planning of chemical reactions. 

In 1967, work was presented from a Sheffield group on indexing chemical reactions for database budding. In 1969, a Harvard group presented its first steps in the development of a system for computer-assisted synthesis design. Soon afterwards, groups at Brandeis University and TU Munich, Germany, presented their work in this area. 

How do chemists find a pathway to the synthesis of a new organic compound They try to find suitable starting materials and powerful reactions for the synthesis of the target compound. Thus, synthesis design and chemical reactions are deeply linked, since a chemical reaction is the instrument by which chemists synthesize their compounds synthesis design is a chemist s major strategy to find the most suitable procedure for a synthesis problem. 

Reaction prediction treats chemical reactions in their forward direction, and synthesis design in their backward, retrosynthetic direction,... 

A second scheme uses a database of known chemical reactions. This more often results in synthesis routes that will work. However, this occurs at the expense of not being able to suggest any new chemistry. This method can also give many possible synthesis routes, not all of which will give acceptable yield or be easily carried out. The quality of results will depend on the database of known reactions and the means for determining which possible routes are best. These are often retro synthetic algorithms, which start with the desired product and let the researcher choose from a list of possible precursors.
