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.

The Mechanism of the ortho-Methylation of Nitrobenzenes by Dimethylsulfonium Methylide was written by Haiss, Peter;Zeller, Klaus-Peter. And the article was included in European Journal of Organic Chemistry in 2011.Related Products of 725266-66-0 The following contents are mentioned in the article:

Nitrobenzenes carrying an ortho substituent are selectively methylated at the free ortho position by reaction with dimethylsulfonium methylide. The importance of the ortho substituent is demonstrated by the failure of the methylation of nitrobenzene and 3- and 4-nitroanisole. This is explained by the out-of-plane geometry of the nitro group in the ortho-substituted derivative, which enables a specific interaction between the ylide and the nitro group favorable for attack of the methylide C atom at the neighboring free ortho position. As shown by appropriate deuterium-labeling studies, the addition is followed by an E1-like β-elimination with displacement of di-Me sulfide and subsequent protonation of the elimination product.
