Demjanov Rearrangement
The Demjanov rearrangement is a chemical reaction named after the Russian chemist Nikolai Demjanov. It involves the rearrangement of an alkylidene cyclopropane to form a different alkylidene cyclopropane. This rearrangement is an important synthetic tool in organic chemistry, particularly for the construction of cyclic compounds with increased ring size or different substitution patterns. The general…
Balz-Schiemann Reaction
The Balz-Schiemann reaction, also known as aryl diazonium salt decomposition, is a chemical reaction used to replace a diazonium group (RN2+) with a halogen atom on an aromatic ring. It is named after the German chemists Balz and Schiemann, who first described the reaction in the early 20th century. The general reaction scheme for the…
