Advanced multidimensional NMR techniques have been employed to investigate the intramolecular hydrogen bonds (HBs) in a series of N,N?-([1,1?-binaphthalene]-2,2?-diyl)bis(benzamide) derivatives, with the site-specific substitution of different functional groups. The existence of intramolecular HBs and the elimination of any molecular aggregation and possible intermolecular HBs are ascertained by various experimental NMR techniques, including solvent polarity dependent modifications of HB strengths. In the fluorine substituted derivative, direct evidence for the engagement of organic fluorine in HB is obtained by the detection of heteronuclear through-space correlation and the coupling between two NMR active nuclei where the transmission of spin polarization is mediated through HBs (1hJFH). The extent of reduction in the strength of 1hJFH on dilution with high polarity solvents directly provided the qualitative measure of HB strength. The HB, although becoming weakened, does not get nullified even in pure high polarity solvent, which is attributed to the structural constraints. The rate of exchange of a labile hydrogen atom with the deuterium of the solvent permitted the measurement of their half-lives, that are correlated to the relative strengths of HBs. The experimental NMR findings are further validated by XRD and DFT-based theoretical computations, such as, NCI and QTAIM.

Synthetic Route of 21436-03-3. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 21436-03-3, Name is (1S,2S)-Cyclohexane-1,2-diamine

Porous organic nanocages (POCs) have received great concern in diverse areas recently. However, a long reaction time as well as a toxic catalyst or solvents are still used to synthesize POCs, which may limit their broad applications. In addition, the synthesis of modified POCs will largely promote and expand their applications. Here we report a rapid, green, and catalyst-free method to synthesize model nano-POC CC3R and modified CC3S to tune their selectivity and to expand their applications in chiral gas chromatographic (GC) separation of many challengeable chiral alcohols. The nanosized CC3R is successfully synthesized via an ethanolic refluxing method within 4 h without any toxic catalyst or inert gas protection. The prepared CC3R coated capillary column provides good resolution and selectivity to diverse chiral alcohols. The mirrored CC3S and hydroxyl-modified CC3R-OH are also designed and synthesized via the ethanolic refluxing method to tune their selectivity and resolution for chiral alcohols. The introduction of hydroxyl groups into CC3R-OH nanocages largely enhanced their hydrogen-bonding forces to chiral alcohols, leading to the improved resolution and selectivity for chiral alcohols, which revealed the promise of modified POCs in chiral separation. This work may promote the synthesis, modification, and chiral chromatographic application of POCs.
