And the article was included in European Journal of Organic Chemistry in 2021.Product Details of 139139-80-3 The following contents are mentioned in the article:

Copper(I)-catalyzed N-arylation (both N¹– and N³-) of hydantoins with diaryliodonium salts as aryl partners at room temperature is reported. The transformation allows diverse scopes on both hydantoins and diaryliodonium salts delivering functionalized N³-arylated products under mild reaction conditions. The presence of hydrogens at C⁵– and N¹– position of the hydantoin does not lead to other side products. Chiral hydantoins can also be synthesized via this methodol. Sterically complicated ortho-substituted diaryliodonium salts are tolerated and delivered challenging ortho-arylated products. In addition, this strategy can also be effectively extended to N¹-arylation of hydantoins. This study involved multiple reactions and reactants, such as Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3Product Details of 139139-80-3).

Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3) belongs to iodide derivatives. Indole could be stereoselectively alkylated with chiral cyclopentyl sulfone reagent.

The selective C(sp³)-H bond functionalization was an ideal and atom-economical method in organic synthesis. In this work, 2-aminopyrimidines, e.g., I were generated from a Cu-catalyzed reaction between carbodiimides and diaryliodonium salts, by cleavage of four C(sp³)-H, one C-N, and one C=N bonds in the carbodiimides.

An efficient transition-metal-free strategy to synthesize 2-aryloxypyridine derivatives was developed by a selective O-arylation of 2-pyridones with diaryliodonium salts.
