The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts. It is named after the Swiss chemist Traugott Sandmeyer. An aromatic (or heterocyclic) amine quickly reacts with a nitrite to form an aryl diazonium salt, which decomposes in the presence of copper(I) salts, such as copper(I) chloride, to form the desired aryl halide. The reaction is a radical-nucleophilic aromatic substitution.

Sandmeyer's reaction is used to create aryl halides from dazonium salts. Any of the various copper salts are able to be used for this reaction.
What do you mean by reagents in chemistry?
Chemical compounds used in laboratory are frequently called reagents.
Can chemicals and reagents go bad?
Yes only some... It depends
Electrophilic and Nucleophilic Reagents?
ELECTROFILIC REAGENTS:It is the combination of two words(electro means electron and phile means loving).Therefore those reagents that contain positive charge on it are called eletrophilic reagents. These reagents have the property of attacking on the negative part of the other substance.Some of the reagents are(NO2+ ,SO3+) NUCLEOPHILIC REAGENTS:Combination(nucleo means nucleus and phuile means loving)
Why are Grignard reagents synthesized in an ether medium?
Grignard reagents are stable in ether medium. Ether generally forms an adduct with Grignard reagents. In addition, if solvents containing acidic hydrogens are present, Grignard reagents are decomposed to the corresponding hydrocarbon.
Why do you keep reagents on ice?
Reagents are kept on ice to prevent denaturation or any form of unwanted reactions.
In what proportion do the reagents be added to make 1 liter solution of silver nitrate?
depends what reagents you are using. Look at the balanced chemical equation, the numbers in front of the reagents show you their respective proportions
What is different between electrophilic and nucleophilic substation?
Electrophilic reagents are chemical species which in the course of chemical reactions, acquire electrons or a share in electrons from other molecules or ions. Nucleophilic reagents do the opposite of electrophilic reagents.
What are the release dates for The Reagents - 2013?
The Reagents - 2013 was released on: USA: 10 October 2013 (Los Angeles, California)
What substances do you have at the beginning of a chemical reaction?
The substances you have at the beginning of a chemical reaction are the reactants or the reagents.
How many reagents are there in stoichiometry?
Since a "reagent" is synonymous with "chemical", there are as many reagents as there are chemicals - pretty much a near-infinite list.
