On July 20, 2022, Kwon, Tae-woo; Song, Bo; Nam, Kwan Woo; Stoddart, J. Fraser published an article.Reference of 1,4-Dimethoxybenzene The title of the article was Mechanochemical Enhancement of the Structural Stability of Pseudorotaxane Intermediates in the Synthesis of Rotaxanes. And the article contained the following:

Mechanochem. syntheses of rotaxanes have attracted considerable attention of late because of the superior reaction rates and higher yields associated with their production compared with analogous reactions carried out in solution Previous investigators, however, have focused on the demonstration of the mechanochem. syntheses of rotaxanes per se, rather than on studying the solid-phase host-guest mol. interplay related to their rapid formation and high yields. In this investigation, the lower yields of rotaxanes prepared in solution were attributed to the limited concentration and a desolvation energy penalty that must be compensated for by host-guest interactions during complexation that precedes the templation leading to rotaxane formation. It follows that, if the desolvation energy can be removed and higher concentrations can be attained, even weak host-guest interactions can drive the complexation of host and guest mols. efficiently. In order to test this hypothesis, two host-guest pairs of permethylated pillar[5]arene/ 1,6-diaminohexane and permethylated pillar[5]arene/ 2,2′-(ethylenedioxy)bis(ethylamine) have been chosen for the simple reason that they exhibit extremely low binding constants (2.7 ± 0.4 M-1 when 1,6-diaminohexane is the guest and <0.1 M-1 when 2,2'-(ethylenedioxy)bis(ethylamine) is the guest in CDCl3; i.e., ostensibly no pseudorotaxane formation is observed). It can be argued that the amount of pseudorotaxanes formed in the solid state is responsive to mech. treatments or otherwise and changes in temperature during stoppering reactions. Compared to the amount of pseudorotaxanes that can be obtained in solution, large quantities of pseudorotaxanes are formed in the solid state because of concentration and desolvation effects. This mechanochem. enhancement of pseudorotaxane formation is referred to as a self-correction in the current investigation. Rotaxanes based on permethylated pillar[5]arene/ 1,6-diaminohexane and permethylated pillar[5]arene/ 2,2'-(ethylenedioxy)bis(ethylamine) have been synthesized in much higher yields compared to those obtained in solution, aided and abetted by self-correction effects during mech. treatments and heating at a mild temperature of 50°C. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Reference of 1,4-Dimethoxybenzene

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.
