《ZnMe2-Mediated, Direct Alkylation of Electron-Deficient N-Heteroarenes with 1,1-Diborylalkanes: Scope and Mechanism》 was written by Jo, Woohyun; Baek, Seung-yeol; Hwang, Chiwon; Heo, Joon; Baik, Mu-Hyun; Cho, Seung Hwan. Formula: C13H26B2O4This research focused onzinc promoted regioselective alkylation pyridine quinoline diborylalkane. The article conveys some information:

The regioselective, direct alkylation of electron-deficient N-heteroarenes is, in principle, a powerful and efficient way of accessing alkylated N-heteroarenes that are important core structures of many biol. active compounds and pharmaceutical agents. Herein, we report a ZnMe2-promoted, direct C2- or C4-selective primary and secondary alkylation of pyridines and quinolines using 1,1-diborylalkanes as alkylation sources. While substituted pyridines and quinolines exclusively afford C2-alkylated products, simple pyridine delivers C4-alkylated pyridine with excellent regioselectivity. The reaction scope is remarkably broad, and a range of C2- or C4-alkylated electron-deficient N-heteroarenes are obtained in good yields. Exptl. and computational mechanistic studies imply that ZnMe2 serves not only as an activator of 1,1-diborylalkanes to generate (α-borylalkyl)methylalkoxy zincate, which acts as a Lewis acid to bind to the nitrogen atom of the heterocycles and controls the regioselectivity, but also as an oxidant for rearomatizing the dihydro-N-heteroarene intermediates to release the product.Bis[(pinacolato)boryl]methane(cas: 78782-17-9Formula: C13H26B2O4) was used in this study.

Bis[(pinacolato)boryl]methane(cas: 78782-17-9) belongs to organoboron compounds.Formula: C13H26B2O4 Organoboron compounds have been a cornerstone of synthetic transformations for decades.

Computed Properties of C9H13NOOn November 2, 2020 ,《Site-Specific C(sp3)-H Aminations of Imidates and Amidines Enabled by Covalently Tethered Distonic Radical Anions》 appeared in Angewandte Chemie, International Edition. The author of the article were Zhao, Rong; Fu, Kang; Fang, Yuanding; Zhou, Jia; Shi, Lei. The article conveys some information:

The utilization of N-centered radicals to synthesize nitrogen-containing compounds has attracted considerable attention recently, due to their powerful reactivities and the concomitant construction of C-N bonds. However, the generation and control of N-centered radicals remain particularly challenging. We report a tethering strategy using SOMO-HOMO-converted distonic radical anions for the site-specific aminations of imidates and amidines with aid of the non-covalent interaction. This reaction features a remarkably broad substrate scope and also enables the late-stage functionalization of bioactive mols. Furthermore, the reaction mechanism is thoroughly investigated through kinetic studies, Raman spectroscopy, ESR spectroscopy, and d. functional theory calculations, revealing that the aminations likely involve direct homolytic cleavage of N-H bonds and subsequently controllable 1,5 or 1,6 hydrogen atom transfer. The experimental part of the paper was very detailed, including the reaction process of 2-Amino-2-(4-methylphenyl)ethan-1-ol(cas: 157142-48-8Computed Properties of C9H13NO)

Product Details of 20880-92-6On June 8, 2022, Zhou, Xukai; Yu, Tingting; Dong, Guangbin published an article in Journal of the American Chemical Society. The article was 《Site-Specific and Degree-Controlled Alkyl Deuteration via Cu-Catalyzed Redox-Neutral Deacylation》. The article mentions the following:

A Cu-catalyzed degree-controlled deacylative deuteration of diverse alkyl groups with the methylketone (acetyl) moiety as a traceless activating group was reported. The use of N-methylpicolino-hydrazonamide (MPHA) promotes efficient aromatization-driven C-C cleavage. Mono-, di-, and trideuteration at specific sites was selectively achieved. The reaction is redox-neutral with broad functional group tolerance. The utility of this method was demonstrated in forming a complete set of deuterated Et groups, merging with the Diels-Alder reaction, a net devinylative deuteration, and the synthesis of the d2-analog of Austedo. In the part of experimental materials, we found many familiar compounds, such as ((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol(cas: 20880-92-6Product Details of 20880-92-6)

In 2022,Physical Chemistry Chemical Physics included an article by Shinkai, Takahiro; Hsu, Po-Jen; Fujii, Asuka; Kuo, Jer-Lai. Formula: C3H5F3O. The article was titled 《Infrared spectroscopy and theoretical structure analyses of protonated fluoroalcohol clusters: the impact of fluorination on the hydrogen bond networks》. The information in the text is summarized as follows:

To explore the impact of fluorination on the hydrogen bond networks of protonated alkylalcs., IR spectroscopy and theor. computations of protonated 2,2,2-trifluoroethanol clusters, H+(TFE)n, (n = 4-7), were performed. It has been demonstrated that the development of the hydrogen bond networks from a linear type to cyclic types occurs in this size region for the protonated alkylalc. clusters. In contrast, IR spectroscopy of H+(TFE)n in the OH/CH stretch region clearly indicated that the linear type structures are held in the whole size range, irresp. of temperature of the clusters. The extensive stable isomer structure search of H+(TFE)n based on our latest sampling approach supported the strong preference of the linear type hydrogen bond networks. Detailed analyses of the free OH stretching vibrational bands evidenced the intra- and intermol. OH···FC interactions in the clusters. In addition, IR spectra of protonated clusters of 2,2-difluoroethanol, 2,2-difluoropropanol, and 3,3,3-trifluoropropanol were measured for n = 4 and 5, and their spectra also indicated the effective inhibition of the cyclic hydrogen bond network formation by the fluorination.3,3,3-Trifluoropropan-1-ol(cas: 2240-88-2Formula: C3H5F3O) was used in this study.
