Stephen K. published an article.Application In Synthesis of 2-Methylanisole The title of the article was A Metal-Free Direct Arene C-H Amination. And the article contained the following:

Here, a metal-free arene e.g., mesitylene C-H amination using hydroxylamine derivatives 4-(CH3)C6H5S(O)2ON(R)R1 (R = H, Me; R1 = Me, Boc, Bn, etc.) under benign conditions was reported. A charge transfer interaction between the aminating reagents and the arene substrates enables the chemoselective amination of the arene, even in the presence of various functional groups. Oxygen was crucial for an effective conversion and its accelerating role for the electron transfer step was proven exptl. In addition, this was rationalized by a theor. study which indicated the involvement of a dioxygen-bridged complex with a “Sandwich-like” arrangement of the aromatic starting materials and the aminating agents at the dioxygen mol. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Application In Synthesis of 2-Methylanisole

And the article contained the following:

A novel cascade annulation of 1,7-diynes I [R2 = R3 = Ph, R4 = H, Y = NBn; R2 = R3 = Ph, R4 = H, Y = O; R2 = Ph, 4-MeOC6H4, 4-BrC6H4, 2-thiophenyl, cyclopropyl, R3 = Ph, 4-MeOC6H4, 4-ClC6H4 R4 = H, Y = NMe; R2 = Ph, R3 = Ph, R4 = Me, Cl, Y = NMe] with water has been developed for the synthesis of furo[3,4-c]quinolin-4(5H)-one skeletons II with high atom- and step-economy.

Dal Poggetto, Guilherme; Favaro, Denize C.; Nilsson, Mathias; Morris, Gareth A.; Tormena, Claudio F. published an article in 2014, the title of the article was 19F DOSY NMR analysis for spin systems with nJFF couplings.Electric Literature of 321-28-8 And the article contains the following content:

NMR is a powerful method for identification and quantification of drug components and contaminations. These problems present themselves as mixtures, and here, one of the most powerful tools is DOSY. DOSY works best when there is no spectral overlap between components, so drugs containing fluorine substituents are well-suited for DOSY anal. as 19F spectra are typically very sparse. Here, the authors demonstrate the use of a modified 19F DOSY experiment (from the Oneshot sequences) for various fluorinated benzenes. For compounds with significant nJFF coupling constants, as is common, the undesirable J-modulation can be efficiently suppressed using the Oneshot45 pulse sequence. This study highlights 19F DOSY as a valuable and robust method for anal. of mol. systems containing fluorine atoms even where there are large fluorine-fluorine couplings.
