Organic Reaction
Organic reactions are chemical reactions involving organic compounds. The basic organic chemistry reaction types are addition reactions, elimination reactions, substitution reactions, pericyclic reactions, rearrangement reactions, Mechanistic Organic Photochemistry, photochemical reactions and organic redox reaction, redox reactions. In organic synthesis, organic reactions are used in the construction of new organic molecules. The production of many man-made chemicals such as drugs, plastics, food additives, fabrics depend on organic reactions. The oldest organic reactions are combustion of organic fuels and saponification of fats to make soap. Modern organic chemistry starts with the Wöhler synthesis in 1828. In the history of the Nobel Prize in Chemistry awards have been given for the invention of specific organic reactions such as the Grignard reaction in 1912, the Diels-Alder reaction in 1950, the Wittig reaction in 1979 and olefin metathesis in 2005.

James Crafts
James Mason Crafts (March 8, 1839 – June 20, 1917) was an American chemist, mostly known for developing the Friedel–Crafts alkylation and acylation reactions with Charles Friedel in 1876. Biography James Crafts, the son of Royal Altamont Crafts and Marianne Mason (daughter of Senator Jeremiah Mason), was born in Boston, Massachusetts and graduated from Harvard University in 1858. Although he never received his Ph.D., he studied chemistry in Germany at the Academy of Mines (1859) of Freiberg, and served as an assistant to Robert Bunsen at Heidelberg, and then with Wurtz in Paris (1861). It was in Paris that Crafts first met Charles Friedel, with whom he later carried out some of his most successful research. Crafts returned to the United States in 1865. In 1868, he was appointed as the first professor of chemistry at the newly founded Cornell University in Ithaca, New York, where he remained until 1870. During the following four years Crafts served as professor of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Friedel's Law
Friedel's law, named after Georges Friedel, is a property of Fourier transforms of real functions. Given a real function f(x), its Fourier transform :F(k)=\int^_f(x)e^dx has the following properties. *F(k)=F^*(-k) \, where F^* is the complex conjugate of F. Centrosymmetric points (k,-k) are called Friedel's pairs. The squared amplitude (, F, ^2) is centrosymmetric: * , F(k), ^2=, F(-k), ^2 \, The phase \phi of F is antisymmetric: * \phi(k) = -\phi(-k) \,. Friedel's law is used in X-ray diffraction, crystallography and scattering from real potential within the Born approximation Generally in scattering theory and in particular in quantum mechanics, the Born approximation consists of taking the incident field in place of the total field as the driving field at each point in the scatterer. The Born approximation is named a .... Note that twin operation( ''Opération de maclage'') is equivalent to an inversion centre and the intensities from the individuals are equivalent ...
