Important Named Reactions in Organic Chemistry

In the field of organic chemistry, name reactions refer to the chemical reactions that are named after the people who discovered or developed them. Amongst the tens of thousands of organic chemical reactions, there exist hundreds of reactions that are known well enough to be named after their discoverers or developers.

The study of named organic chemical reactions is a vital part of organic chemistry as they provide insight into the types of reactions different functional groups participate in. they also have numerous applications in the laboratory as well as in industry. Therefore, here are 4 important named reactions in the field of organic chemistry.

Grignard Reaction – the Grignard reaction is an organometallic chemical reaction. In this reaction, alkyl, vinyl, or even aryl magnesium halides (which are commonly referred to as Grignard reagents) are added to the carbonyl group of an aldehyde or a ketone.

Sabatier Reaction – the Sabatier reaction is also referred to as the Sabatier process and is named after its discoverer – the French chemist Paul Sabatier, who discovered it in the year 1897 along with Jean-Baptiste Senderens.

Wittig Reaction – the Wittig reaction refers to the chemical reaction of an aldehyde or a ketone with triphenylphosphoniumylide to yield an alkene along with triphenylphosphine oxide.

Cannizzaro Reaction –  the Cannizzaro reaction is an organic chemical reaction in which a base-induced disproportionation of two molecules of an aldehyde occurs to give a carboxylic acid and a primary alcohol

Sandmeyer Reaction: It is a chemical reaction which is used to synthesize aryl halides from aryl diazonium salts. This reaction is a method for substitution of an aromatic amino group by preparing diazonium salt that is followed by its displacement and copper salts often catalyze it. Gattermann Reaction: Bromine and Chlorine can be present in the benzene ring by preparing the benzene diazonium salt solution with similar halogen acid present with copper powder. This is knows as the Gatterman reaction

Balz-Schiemann Reaction: When arene-diazonium chloride is prepared with fluoroboric acid, arene diazonium fluoroborate is precipitated and decomposes to yield aryl fluoride which on heating.

Finkelstein Reaction: In this reaction Alkyl iodides are prepared easily by the reaction of alkyl chlorides with Nal in dry acetone.

Swarts Reaction: When alkyl chloride is heated in the presence of a metallic fluoride like AgF, Hg2F2, SbF3 or CoF2, we get alkyl fluorides.

Wurtz Reaction: When Alkyl halides get reacted with sodium with dry ether, we get hydrocarbons that include the double number of carbon atoms present in the halide. This is known as the Wurtz reaction.

Wurtz-Fittig Reaction: When a mixture of alkyl halide and aryl halide gets treated with sodium in dry ether, we get an alkyl arene.

Fittig Reaction: Aryl halides prepared with sodium in dry ether to give analogous compounds where two aryl groups joined.

Friedel-Crafts alkylation Reaction: Benzene is prepared with an alkyl halide in the presence of anhydrous aluminum chloride to give Alkylbenzene.
