Chemical synthesis using green chemistry promotes the design of new synthetic methods and apparatus that simplify operations and seeks environmentally benign solvents. Key principles include atom economy , which aims to incorporate all reactant atoms into the final product, and the reduction of waste and inefficiencies in chemical processes.
Total synthesis targets can also be organometallic or inorganic. [5] [6] While total synthesis aims for complete construction from simple starting materials, modifying or partially synthesizing these compounds is known as semisynthesis. Natural product synthesis serves as a critical tool across various scientific fields.
Organic synthesis is an important chemical process that is integral to many scientific fields. Examples of fields beyond chemistry that require organic synthesis include the medical industry, pharmaceutical industry, and many more. Organic processes allow for the industrial-scale creation of pharmaceutical products.
Total synthesis, the complete organic synthesis of complex organic compounds, usually without the aid of biological processes; Convergent synthesis or linear synthesis, a strategy to improve the efficiency of multi-step chemical syntheses; Dehydration synthesis, a chemical synthesis resulting in the loss of a water molecule
Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur. The substance (or substances) initially involved in a chemical reaction are called reactants or reagents .
For example, in aqueous conditions the competing reactions in the cell are the formation of oxygen at the anode and hydrogen at the cathode. In this case a graphite anode and lead cathode could be used effectively because of their high overpotentials for oxygen and hydrogen formation respectively. Many other materials can be used as electrodes.
The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol . This reaction was developed by Alexander Williamson in 1850. [ 2 ] Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an S N 2 reaction .
A large scale application of the Ritter reaction is in the synthesis of tert-octylamine, by way of the intermediate formamide.This process was originally described by Ritter in 1948, [11] and an estimated 10,000 tons/y (year: 2000) of this and related lipophilic amines are prepared in this way. [12]
