Lefranc, Julien; Minassi, Alberto; Clayden, Jonathan published an article in 2013, the title of the article was Carbolithiation of N-alkenyl ureas and N-alkenyl carbamates.Reference of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate And the article contains the following content:

N-(alkenyl)urea derivatives and N-(alkenyl)carbamates, like other N-acyl enamines, are typically nucleophilic at their β-carbon. However, by incorporating an α-aryl substituent, the authors show that they will also undergo attack at the β-carbon by organolithium nucleophiles, leading to the products of carbolithiation. The carbolithiation of (E)-(alkenyl)urea and (Z)-(alkenyl)urea derivatives is diastereoselective and N-tert-butoxycarbonyl N-alkenyl carbamates give carbolithiation products that may be deprotected in situ to provide a new connecting route to hindered amines. The title compounds thus formed included rel-N-(4-methoxyphenyl)-N,N’-dimethyl-N’-[(1R,2R)-2-methyl-1-phenylhexyl]urea (I) and related substances, such as carbamate esters, N-methyl-N-(3-methyl-1-phenylbutyl)carbamic acid 1,1-dimethylethyl ester. The synthesis of the target compounds was achieved by a reaction of (butyl)lithium, (tert-butyl)lithium, etc. with N,N’-dimethyl-N-phenyl-N’-(1-phenylethenyl)urea derivatives, [N(E)]-N-(1-phenylethylidene)methanamine, N-[(phenyl)alkenyl]carbamic acid esters. The experimental process involved the reaction of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate(cas: 14602-86-9).Reference of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate

On April 7, 2017, Adhikari, Arijit A.; Suzuki, Tamie; Gilbert, Reesheda T.; Linaburg, Matthew R.; Chisholm, John D. published an article.Recommanded Product: 98946-18-0 The title of the article was Rearrangement of Benzylic Trichloroacetimidates to Benzylic Trichloroacetamides. And the article contained the following:

The rearrangement of allylic trichloroacetimidates is a well-known transformation, but the corresponding rearrangement of benzylic trichloroacetimidates has not been explored as a method for the synthesis of benzylic amines. Conditions that provide the trichloroacetamide product from a benzylic trichloroacetimidate in high yield have been developed. Methods were also investigated to transform the trichloroacetamide product directly into the corresponding amine, carbamate, and urea. A cationic mechanism for the rearrangement is implicated by the available data. The experimental process involved the reaction of tert-Butyl trichloroacetimidate(cas: 98946-18-0).Recommanded Product: 98946-18-0

On August 31, 2020, Jiang, Mingjie; Sun, Yue; Ning, Jiaoyi; Chen, Youquan; Wu, Yuting; Hu, Zhao; Shuja, Ahmed; Meng, Hong published an article.Application of 80-07-9 The title of the article was Diphenyl sulfone based multicolored cathodically coloring electrochromic materials with high contrast. And the article contained the following:

A series of multicolored cathodically coloring electrochromic (EC) materials based on di-Ph sulfone (DPS) moiety were synthesized and characterized. Herein two electron donors, N1,N1,N3,N3-tetraphenylbenzene-1,3-diamine (TPA) and 1,3-di (9H-carbazol-9-yl)benzene (MCP), were employed to construct donor-acceptor (D-A) or donor-acceptor-donor (D-A-D) small mols. with DPS as the acceptor. These small mols. can achieve excellent EC properties, including multicolored electrochromism, high optical contrast over 90%, high coloration efficiency and good cyclic stability. Remarkably, the color of MCP-DPS could be switched from colorless to three primary colors gradually, containing green, magenta and yellow driven by the 3-step reversible reduction, meeting the requirements of full-color EC display.

On March 5, 2018, Pandey, Archana; Verma, Chandrabhan; Singh, B.; Ebenso, Eno E. published an article.Related Products of 99-60-5 The title of the article was Synthesis, characterization and corrosion inhibition properties of benzamide-2-chloro-4-nitrobenzoic acid and anthranilic acid-2-chloro-4-nitrobenzoic acid for mild steel corrosion in acidic medium. And the article contained the following:

The present study deals with the synthesis of two new compounds namely, benzamide – 2-chloro-4-nitrobenzoic acid (BENCNBA) and anthranilic acid-2-chloro-4-nitrobenzoic acid (AACNBA) using solid phase reactions. The phase diagram studies revealed that formation of the studied compounds occurs in 1:1 molar ratio. The synthesized compounds were characterized using several spectral techniques such as FT-IR, 1H and 13C NMR, UV-Vis, powder x-ray diffraction (PXRD). Single crystal x-ray diffraction (SCXRD) study showed that both BENCNBA and AACNBA compounds crystallize in triclinic crystal system with P-1 space group. Further, the presence of intermol. hydrogen bonding between the constituent components was also supported by single crystal x-ray diffraction (SCXRD) method. Heat of mixing, entropy of fusion, roughness parameter, interfacial energy and excess thermodn. functions were computed using the enthalpy of fusion values derived from differential scanning calorimeter (DSC) study. The inhibition effect of BENCNBA and AACNBA on the mild steel corrosion in hydrochloric acid solution was tested using electrochem. methods. Electrochem. impedance spectroscopy (EIS) study revealed that both BENCNBA and AACNBA behaved as interface corrosion inhibitors and showed maximum inhibition efficiencies of 95.71% and 96.42%, resp. at 400 ppm (1.23 × 10-3 M) concentration Potentiodynamic polarization (PDP) measurements suggested that BENCNBA and AACNBA acted as mixed type corrosion inhibitors. EIS and PDP results showed that BENCNBA and AACNBA act as efficient corrosion inhibitors for mild steel and their inhibition efficiencies enhances on increasing their concentrations The experimental process involved the reaction of 2-Chloro-4-nitrobenzoic acid(cas: 99-60-5).Related Products of 99-60-5
