Acylation reactions are chemical reactions in which an acyl group (-COCH3) is added to a molecule. The acyl group can be derived from an acid chloride (RCOCl), an anhydride (RCOOR), or a carboxylic acid (RCOOH) with an activating agent such as DCC (dicyclohexylcarbodiimide) or SOCl2 (thionyl chloride). One common type of acylation reaction is the…
Alkylation is a chemical reaction in which an alkyl group (a group of carbon and hydrogen atoms) is added to a molecule. This process is commonly used in organic chemistry to introduce new alkyl groups to a molecule in order to modify its properties or reactivity. Alkylation reactions can be carried out using a variety…
The Carbylamine reaction, also known as the isocyanide test or Hofmann’s isocyanide test, is a chemical test used to detect the presence of primary amines in a given compound. The test was discovered by August Wilhelm von Hofmann in 1861 and is based on the reaction of primary amines with chloroform and a strong base,…

The Sandmeyer reaction is a classic organic chemical reaction that is used to synthesize aryl halides from aryl diazonium salts. The reaction is named after Traugott Sandmeyer, who first reported it in 1884. Amines can be used as starting materials in the Sandmeyer reaction to synthesize aryl halides bearing amino groups. The reaction proceeds via…
Azo coupling reaction is a type of organic reaction that involves the reaction of a diazonium salt of an aromatic amine with another aromatic compound that contains an electron-rich group, such as an -OH or -NH2 group. The reaction results in the formation of an azo compound, which contains a -N=N- group. The general reaction…
The reaction with nitrous acid (HNO2) depends on the conditions and the nature of the compound with which it reacts. In general, nitrous acid is a weak acid and a good oxidizing agent. Here are a few examples of reactions with nitrous acid: CH3CH2OH + HNO2 → CH3CH2ONO C6H5NH2 + HNO2 → C6H5N2Cl + 2H2O…
The Gabriel phthalimide synthesis is a method for the preparation of primary amines from alkyl halides. The reaction involves the formation of an N-alkyl phthalimide intermediate, followed by its hydrolysis under basic conditions to give the corresponding primary amine. The general reaction scheme is as follows: R-X + phthalimide → R-NH-phthalimide R-NH-phthalimide + base →…
The Hoffmann bromamide degradation is a chemical reaction that involves the conversion of a primary amide to a primary amine by treating it with bromine and sodium or potassium hydroxide. The reaction proceeds via a rearrangement of the intermediate isocyanate to an amine. The reaction is named after August Wilhelm von Hofmann, who discovered it…
Amines and nitriles are two types of organic compounds. Amines are organic compounds that contain nitrogen atoms bonded to one or more alkyl or aryl groups. They are classified according to the number of alkyl or aryl groups attached to the nitrogen atom. Amines can be primary (one alkyl or aryl group), secondary (two alkyl…
