Aryl halides react with metals, generally lithium or magnesium, to give organometallic derivatives that function as sources of aryl anions. By the metal-halogen exchange reaction, aryl halides are converted to aryl lithium compounds.

Aryl iodides are important synthetic building blocks in organic chemistry that are mainly used for cross-coupling and related reactions, (1) such as the Mizoroki–Heck reaction, (2) Sonogashira coupling, (3) Suzuki–Miyaura cross-coupling, (4) and Ullmann condensation.

2023年1月23日 · This page looks at the ways of making the aryl halides, chlorobenzene, bromobenzene and iodobenzene. Making chlorobenzene Benzene reacts with chlorine in the presence of a catalyst, replacing one of the hydrogen atoms on the ring by a chlorine atom.

2023年8月1日 · Mechanistic investigation suggests that electron donor−acceptor (EDA) complex formation was mediated by halogen bonding between phenoxide and aryl iodide followed by Irradiation of the EDA complex under visible light generating the corresponding aryl radical, which then abstracts a hydrogen atom from sp 3 carbon of both cyclic and acyclic ...

A convenient and efficient visible-light-induced decarboxylative iodination of aromatic carboxylic acids provides the corresponding aryl iodides in good yields. The method offers simple and mild conditions, high efficiency, wide substrate scope and tolerates various functional groups.

ABSTRACT: A metal- and base-free method is developed for the synthesis of aryl iodides from arylhydrazine hydro-chlorides and iodine. A wide variety of aryl iodides can be conveniently synthesized by an equimolar reaction of arylhydrazine hydrochlorides and I2 in dimethyl sulfoxide at. 60 C for 6 h. In the iodination step, arylhydrazines are.

Aryl iodides are a class of organic compounds that consist of an aromatic ring (aryl group) bonded to an iodine atom. These compounds are important in the context of nucleophilic aromatic substitution reactions, where the iodine atom can be replaced by a nucleophile.

2012年9月24日 · Here, we describe the identification of reaction conditions under which photocatalysts such as fac -Ir (ppy) 3 can be utilized to form radicals from unactivated alkyl, alkenyl and aryl iodides....

2018年10月8日 · This work illustrates the reductive coupling of electron-rich aryl halides with tertiary alkyl halides under Ni-catalyzed cross-electrophile coupling conditions, which offers an efficient protocol for the construction of all carbon quaternary stereogenic centers. The mild and easy-to-operate reaction tolerates a wide range of functional groups.

2016年9月15日 · The aromatic Finkelstein iodination reaction is a powerful method of preparing valuable aryl iodides from cheap but less reactive aryl bromides and chlorides.
