Selective arylation/annulation cascade reactions of 2-alkynylanilines with diaryliodonium salts

An efficient Cu catalyzed selective arylation/annulation cascade reaction of 2-alkynylanilines with diaryliodonium salts was developed.This reaction was selective to N-arylation instead of C-arylation,which provides a simple synthetic method for N-aryl indoles.

Efficient synthesis of cyclic imides by the tandem N-arylation-acylation and rearrangement reaction of cyanoesters with diaryliodonium salts

Available online An efficient method for the synthesis of multi-substituted cyclic imides was developed with cyanoesters and diaryliodonium salts.This method proceeds through a cascade of N-arylationacylation and rearrangement to give target heterocycles in good yields(up to 99%).This method has the major advantages of a broad substrate scope,excellent functional group compatibility.The strategy was also extended to the fused cyclic imides,such as malonimides,succinimides and glutarimides.

Concise synthesis of xanthones by the tandem etherification——Acylation of diaryliodonium salts with salicylates

An efficient synthetic method for multi-substituted xanthones was developed. The reaction of diaryliodonium salts and salicylates was employed for the preparation of the xanthones. This method proceeded through an intermolecular etherification-acylation to give target heterocycles in good yields（up to 91%）. Multi-substituted xanthones were gained by shifting the substituent of salicylates or diaryliodonium salts

Copper-catalyzed direct oxidation and N-arylation of benzylamines with diaryliodonium salts

An efficient approach for the synthesis of N-arylated amides was developed via copper(Ⅱ) triflate-catalyzed direct oxidation of(aryl)methylamines to primary arylamides by air and subsequent N-arylation by diaryliodonium salts. Various substituted benzylamines could be applied in the reaction, providing a series of N-arylated amides in moderate to good yields. This method showed convenient, practical, and environment friendly advantages.

One-pot synthesis of diarylimidazolium salts from 1H-imidazole

Diarylimidazolium salts （3） were directly synthesized starting from lH-imidazole （1） by a one-pot strategy using diaryliodonium salts as the arylating reagents, lH-Benzimidazole and 1H-1,2,4-triazole are suitable substrates as well to form the corresponding diarylazolium salts.

Hypervalent Iodine in Synthesis 64: Syntheses of Diaryl Selenides and Alkyl Aryl Selenides by Palladium-Catalyzed Arylation of Areneselenyl or Alkaneselenyl Magnesium Bromide with Diaryliodonium Salt

Areneselenyl or alkaneselenyl magnesium bromide reacts rapidly with diaryliodonium salt to give the corresponding diaryl or alkyl aryl selenide in the presence of catalytic amounts of Pd-(PPh3)4 in good yield.
