One-pot synthesis
Under a one-pot reaction is understood in chemistry and technology chemical synthesis, which is characterized in that one possible, all the necessary reagents and solvents at the beginning in a vessel ( Laboratory: round-bottom flask, three-necked flask, Erlenmeyer flasks or the like; technology. Reaction vessel, tank battery, flow tube ) mixed and then allowed to react (usually under stirring / mixing and heating or cooling). Sometimes, individual components in the course of the operation only added (preferably, through a dropping funnel in the laboratory, or any other metering device ). Once the reaction is over, you work on the recognition and so wins the product, often by precipitation, crystallization or distillation.
One-pot reactions require as opposed to multistep syntheses, no isolation of intermediates and generally very little equipment expense. This saves material, time and energy, which is why synthetic chemists and technicians for many important intermediate and final products - choose the reaction conditions so that you can perform the synthesis in one pot - usually with a relatively simple molecular structure. However, complex molecules are built (eg many natural substances ) are often not accessible via one-pot reactions.
The term was transmitted as a one-pot reaction or one-pot synthesis literally into English and is used by the Anglophone literature in the same sense.
