2021年4月9日 · Aryl diazonium salts are versatile building blocks in organic synthesis. In light of the ever-increasing importance of aryl diazonium salts spanning most disciplines of the chemical sciences, we review the recent development of aryl diazonium chemistry over the past seven years (2013–2020).
Diazonium compound - Wikipedia
Diazonium compounds or diazonium salts are a group of organic compounds sharing a common functional group [R−N + ≡N]X − where R can be any organic group, such as an alkyl or an aryl, and X is an inorganic or organic anion, such as a halide. The parent compound where R is hydrogen, is diazenylium.
Aryl Diazonium Salts: Powerful Arylating Agents for Catellani …
2021年11月15日 · As demonstrated in this work, aryl diazonium salts bearing both electron-donating and electron-withdrawing substituents, after in situ transformations with KI into the corresponding iodoarenes, were efficient arylating reagents for …
Nitrate reduction enables safer aryldiazonium chemistry | Science …
The nitrate reduction strategy avoids accumulation of the explosive diazonium salts and gives direct access to the aryl halides without observation of any violent reaction from rapid gas evolution or uncontrolled energy release.

2023年1月23日 · Aryl diazonium salts are important intermediates. They are prepared in cold (0 º to 10 ºC) aqueous solution, and generally react with nucleophiles with loss of nitrogen. Some of the more commonly used substitution reactions are shown in the following diagram.
Selective and energy-efficient electrosynthesis of ethylene
2024年2月9日 · Aryl diazonium salts are well-known electrophiles that have been extensively used for covalent surface modification since their first demonstration, and the electron-withdrawing ability of the ...
In situ Diazonium Salt Formation and Photochemical Aryl‐Aryl …
2024年3月10日 · A novel class of diazonium salts is introduced for the photochemical aryl-aryl coupling to produce (substituted) biphenyls. As common diazonium tetrafluoroborate salts fail, soluble and safe aryl diazonium trifluoroacetates are applied.
A Need for Caution in the Preparation and Application of …
Various aryl and hetero aryl diazonium salts undergo an sp-sp2 cross coupling reaction with alkynyl acid to give good to excellent yields of substituted acetylene derivs. The diazonium salts served as efficient, easily available, and inexpensive aryl surrogates over conventional aryl halides, triflates, oxalate, and sulphamate.
