Who was Von Richter?
Victor von Richter (April 15, 1841 – October 8, 1891) was a German chemist and discovered the von Richter reaction.
What is von Richter rearrangement?
The von Richter reaction, also named von Richter rearrangement, is a name reaction in the organic chemistry. It is named after Victor von Richter, who discovered this reaction in year 1871.
What type of reaction is Sandmeyer reaction?
The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts using copper salts as reagents or catalysts. It is an example of a radical-nucleophilic aromatic substitution….

What is Cine substitution reaction?
A type of substitution reaction in which the entering group takes a position on an atom adjacent to the atom to which the leaving group is attached. See also tele-substitution. From: cine-substitution in A Dictionary of Chemistry » Subjects: Science and technology — Chemistry.
Why is the Sandmeyer reaction important?
The Sandmeyer Reaction is a very important transformation in aromatic chemistry, because it can result in some substitution patterns that are not achievable by direct substitution. Fluorination is possible by using the related Schiemann Reaction.
What do you mean by Sandmeyer reaction?
The Sandmeyer reaction is a versatile synthetic tool by which an amino group on an aromatic ring is replaced with a wide range of substituents by converting an amino group attached to an aromatic ring into a diazonium salt that can be transformed into several functional groups.
What is SNAR mechanism?
SNAr mechanism: An aromatic substitution mechanism featuring nucleophilic addition to an aromatic ring (which destroys the ring’s aromaticity), followed by an elimination step (which restores the lost aromaticity).
What is Sandmeyer gattermann reaction?
Gattermann reaction is a variation of Sandmeyer reaction which the CuCl is replaced by Cu powder. This replacement leads to formation of aryl halide more easily and under mild conditions than Sandmeyer reaction although the yield is reduced.
What is the difference between gattermann and Sandmeyer reaction?
So, the key difference between Sandmeyer reaction and Gattermann reaction is that the Sandmeyer reaction refers to the synthesis of aryl halides from aryl diazonium salts in the presence of copper salts as a catalyst, whereas Gattermann reaction refers to the formylation of aromatic compounds in the presence of a Lewis …
What are Electrophiles explain with the help of an example?
Electrophiles are electron deficient species and can accept an electron pair from electron rich species. Examples include carbocations and carbonyl compounds. A nucleophile is electron rich species and donates electron pairs to electron deficient species. Examples include carbanions, water , ammonia, cyanide ion etc.
