Kolbe Nitrile Synthesis - Organic chemistry

As late as the 1840s, and despite in 1828, some chemists stillbelieved in the doctrine of , according to which a speciallife-force was necessary to create organic compounds. Kolbedeveloped the idea that could be derivedfrom inorganic ones, directly or indirectly, by substitutionprocesses. He validated his theory by converting , in several steps, to (1843-45). Introducing amodified idea of structural , hecontributed to the establishment of . One of the moredramatic successes of his theory was his prediction of theexistence of secondary and tertiary , a conjecture that was soon confirmedby the synthesis of these substances.

The method of carrying out chemical reactions using electricity was developed more than 160 years ago by German chemist Hermann Kolbe. Although electrochemical syntheses are used in the chemical industry, this has so far been a niche technology. One reason is that the electrolysis conditions must be very finely controlled and uniform current input is essential. Due to the sophisticated technical infrastructure, the option of electrosynthesis remained unknown to most chemists. Now, in the 21st century, the green potential of electrochemistry has been rediscovered. It makes sustainable and eco-friendly chemistry possible with very simple means, particularly with the use of surplus power from renewable sources, such as wind or solar energy.

The key compound in the synthesis of aspirin, salicylic acid, is prepared from phenol by a process discovered in the nineteenth century by the German chemist Hermann Kolbe. In the Kolbe synthesis, also known as the Kolbe–Schmitt reaction,sodium phenoxide is heated with carbon dioxide under pressure, and the reaction mixture is subsequently acidified to yield salicylic acid:

Kolbe nitrile synthesis - Revolvy

The Kolbe nitrile synthesis is a method for thepreparation of by reaction of the corresponding with a metal . Aside-product for this reaction is the formation of an because the cyanide ion is an and according to capable of reaction withcarbon or with nitrogen. The reaction is named after .
