Hypervalent iodine in synthesis 85: An efficient method for the synthesis ofN-arylbenzimidazoles by the coppercatalyzed N-arylation of benzimidazole with diaryliodonium salts

Diaryliodonium(III) Salts in One-Pot Double Functionalization of C–IIII and ortho C–H Bonds

Since the 1950s, diaryliodonium(III) salts have been demonstrated to participate in various arylation reactions, forming aryl–heteroatom and aryl–carbon bonds. Incorporating the arylation step into sequential transformations would provide access to...

Domino N-/C- or N-/N-/C-arylation of imidazoles to yield polyaryl imidazolium salts via atom-economical use of diaryliodonium salts

Herein, we disclose a Cu-mediated domino di-/triarylation reaction of imidazoles to efficiently access polyaryl imidazolium salts in a single step by using two aryls as well as an anion of a diaryliodonium salt. The diarylation shows high atom economy and excellent selectivity with unsymmetrical iodonium salts.

Organic Reactions in Ionic Liquids: A Novel Method for the Synthesis of 2-Arylthiobenzothiazoles by the S-Arylation of Benzolthiazole-2-Thiol with Diaryliodonium Salts

2-Arylthiobenzothiazoles were readily prepared in good yields by the S-arylation of benzothiazole-2-thiol with diaryliodonium salts at room-temperature in the ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim]BF4). The ionic liquid can be recycled and reused.

Ionic liquid-Accelerated N-Arylation of Benzoazoles with Diaryliodonium Salts, An Efficient Method for the Synthesis of N-aryl Azoles

N-Arylation of benzoazoles with diaryliodonium salts can be performed in good yields in the room-temperature ionic liquid 1–butyl–3–methylimidazolium tetrafluoroborate ([bmim]BF4), which provides an efficient method for the synthesis of N-arylbenzoazoles. The ionic liquid can be recycled and reused.

Reaction of arenes with iodine in the presence of potassium peroxodisulfate in trifluoroacetic acid. Direct and simple synthesis of diaryliodonium triflates

Diaryliodonium triflates have been directly prepared by reaction of arenes with elemental iodine in good yields by using K2S2O8 and TFA, followed by treatment with NaOTf. This procedure avoids the use of high temperature and severe reaction conditions.
