The Baker–Venkataraman rearrangement refers to the transformation of ortho-acyloxyaryl ketones into the corresponding aryl β-diketones via a rearrangement reaction. It is named after chemists W. Baker and Krishnaswamy Venkataraman. The Baker–Venkataraman rearrangement is one of the most widely used methods for synthesizing chromones, flavones, and isoflavones.

The Schiemann reaction, also known as the Balz–Schiemann reaction, is a transformation in which an aromatic primary amine is converted into an aryl fluoride via a diazonium tetrafluoroborate intermediate under heating or photolytic conditions. The reaction was discovered in 1927 by German chemists Günther Schiemann and Günther Balz, and is...

The Bamford–Stevens reaction refers to the base-catalyzed decomposition of tosylhydrazones derived from aldehydes or ketones to generate alkenes. This reaction was first reported in 1952 by British chemist William Randall Bamford and Scottish chemist Thomas Stevens Stevens, and is named after them. When carried out in aprotic solvents, the reaction...

The Barton–McCombie Reaction is an organic reaction in which a hydroxyl functional group in an organic compound is replaced by a hydrogen atom, forming an alkane. This reaction was discovered in 1975 by British chemists Derek Harold Richard Barton and Stuart W. McCombie, and is named after them. It is...

The Bischler–Napieralski Reaction refers to an intramolecular electrophilic substitution reaction in which β-aryl ethylamides undergo cyclization in the presence of chlorinating reagents to form 1,2-dihydroisoquinoline derivatives. This reaction was first discovered in 1893 by German chemist August Bischler and Swiss chemist Bernard Napieralski during their research on alkaloids. It is...

Bergman Cyclization is a reaction in which enediyne compounds undergo thermal or photochemical cyclization in the presence of a hydrogen donor (such as 1,4-cyclohexadiene) to form substituted benzene derivatives. The reaction is named after American chemist Robert G. Bergman. Due to the limited range of suitable substrates and stringent conditions,...
