Substituent Effects of 2-Pyridones on Selective O-Arylation with Diaryliodonium Salts: Synthesis of 2-Aryloxypyridines under Transition-Metal-Free Conditions was written by Li, Xiao-Hua;Ye, Ai-Hui;Liang, Cui;Mo, Dong-Liang. And the article was included in Synthesis in 2018.Computed Properties of C19H22F3IO3S The following contents are mentioned in the article:

An efficient transition-metal-free strategy to synthesize 2-aryloxypyridine derivatives was developed by a selective O-arylation of 2-pyridones with diaryliodonium salts. The reaction was compatible with a series of functional groups for 2-pyridones and diaryliodonium salts such as halides, nitro, cyano and ester groups. The substituents at the C6-position of 2-pyridones favored O-arylation products because of steric hindrance. The reaction was easily performed on a gram-scale and 6-chloro-2-pyridone was a good precursor to access various unsubstituted 2-aryloxypyridines by dehalogenation. A P2Y₁ lead compound analog I could be prepared in good yield over two steps.

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.
