Check Digit Verification of cas no

The CAS Registry Mumber 119492-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,4,9 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119492-43:
(8*1)+(7*1)+(6*9)+(5*4)+(4*9)+(3*2)+(2*4)+(1*3)=142
142 % 10 = 2
So 119492-43-2 is a valid CAS Registry Number.

Mild and efficient copper-catalyzed N-arylation of alkylamines and N-H heterocycles using an oxime-phosphine oxide ligand

Xu, Lei,Zhu, Di,Wu, Fan,Wang, Rongliang,Wan, Boshun

, p. 6553 - 6560 (2005)

A mild and efficient copper-catalyzed system for N-arylation of alkylamines and N-H heterocycles with aryl iodides using a novel, readily prepared and highly stable oxime-functionalized phosphine oxide ligand was developed. The coupling reactions could even be performed in solvent-free conditions with moderate to good yields.

Novel non-hydrolytic templated sol-gel synthesis of mesoporous aluminosilicates and their use as aminolysis catalysts

Skoda, David,Styskalik, Ales,Moravec, Zdenek,Bezdicka, Petr,Babiak, Michal,Klementova, Mariana,Barnes, Craig E.,Pinkas, Jiri

, p. 24273 - 24284 (2016)

A novel non-hydrolytic sol-gel (NHSG) synthesis of mesoporous aluminosilicate xerogels is presented. The polycondensation between silicon acetate, Si(OAc)4, and tris(dimethylamido)alane, Al(NMe2)3, leads to homogeneous alu

Trimming nanostructured walls while fluorinating their surfaces: A route to making and widening pores of nanoporous materials and efficient catalysts

Duncan, Cole T.,Biradar, Ankush V.,Rangan, Sylvie,Mishler, Richard E.,Asefa, Tewodros

, p. 4950 - 4963 (2010)

We report on the synthesis and characterization of highly ordered mesoporous fluorosilicas (OMFs) and nanoporous and corrugated fluorosilica nanospheres which contain 2.4-7.0 wt % F, corresponding to a loading of 1.3-3.7 mmol/g. Synthesis of these materia

Post-synthesis of Zr-MOR as a robust solid acid catalyst for the ring-opening aminolysis of epoxides

Tang, Bo,Song, Wei-Chao,Li, Sheng-Yang,Yang, En-Cui,Zhao, Xiao-Jun

, p. 13503 - 13511 (2018)

Zirconosilicate with the MOR topology (Zr-MOR) was successfully prepared using a two-step post-synthesis strategy from pre-dealumination of a H-MOR zeolite and subsequent dry impregnation of Cp2ZrCl2. The incorporated Zr species main

Mesoporous carbon as an efficient catalyst for alcoholysis and aminolysis of epoxides

Matos, Inês,Neves, Paulo Duarte,Castanheiro, José Eduardo,Perez-Mayoral, Elena,Martin-Aranda, Rosa,Duran-Valle, Carlos,Vital, Joaquim,Botelho Do Rego, Ana M.,Fonseca, Isabel M.

, p. 24 - 30 (2012)

The ring opening reaction of epoxides by alcohols and amines using mesoporous activated carbon as efficient and environmentally friendly heterogeneous catalyst is reported. Carbon xerogels were synthesized by polymerization of resorcinol and formaldehyde. The surface of the activated carbon was oxidized in liquid phase with HNO3 and then functionalized with H2SO4. Chemical and textural characterization by elemental analysis, pHPZC, TPD, BET and XPS indicates that oxidation in liquid phase is effective in the introduction of strong acid groups in the carbon surface. The functionalization with H2SO4 led to more acid functional groups, as expected. The activated carbons were tested in alcoholysis and aminolysis of epoxides, having been obtained excellent results of conversion and selectivity, both over 95%.

A novel copper framework with amino tridentate N-donor ligand as heterogeneous catalyst for ring opening of epoxides

Huang, Zi-Qing,Xu, Zou-Hong,Liu, Xiao-Hui,Zhao, Yue,Wang, Peng,Liu, Zhi-Qiang,Sun, Wei-Yin

, (2021)

A novel metal–organic framework (MOF) [Cu3L(2,6-NDC)2]·0.5DMF (MOF-Cu-1) was synthesized by solvothermal reaction of copper nitrate trihydrate with 2,6-naphthalenedicarboxylic acid (2,6-H2NDC) and amino tridentate N-donor

First chemo- and stereoselective reduction of imines using trichlorosilane activated with N-formylpyrrolidine derivatives

Iwasaki, Fumiaki,Onomura, Osamu,Mishima, Katsuhiko,Kanematsu, Takefumi,Maki, Toshihide,Matsumura, Yoshihiro

, p. 2525 - 2527 (2001)

Trichlorosilane activated with N-formylpyrrolidine derivatives was found to be an effective reagent for reduction of imines to amines. The reagent showed much higher selectivity toward imino groups than carbonyl groups. The reduction of imines using trichlorosilane activated with optically active N-formylproline derivatives gave enantiomerically enriched amines in moderate optical yields (up to 66% ee).

Amine grafted Fe3O4 immobilized graphene oxide as a recyclable and effectual nanocomposite for the regioselective ring opening reaction

Gupta, Padmini,Garkoti, Charu,Shabir, Javaid,Surabhi,Sah, Digvijay,Mozumdar, Subho

, p. 4013 - 4028 (2021/06/25)

This work describes the synthesis of magnetic graphene oxide (MGO), where iron oxide (Fe3O4) nanoparticles were uniformly deposited over the sheets of the graphene oxide (GO). Further, the introduction of aminopropyltrimethoxysilane (APTMS) on the surface of MGO was successfully done and results in the formation of amine-functionalized magnetic graphene oxide (MGO–NH2). The synthesized heterogeneous magnetic nanocomposite was characterized by numerous physicochemical and morphological techniques such as powder X-ray diffraction, Fourier transform infrared, thermogravimetric analysis, transmission electron microscopy, vibrating sample magnetometer, scanning electron microscopy, CHN analyzer, and energy-dispersive X-ray analysis. The synthesized nanocomposite was proved to be an effectual catalyst in the nucleophilic ring opening reactions of styrene oxide with derivatives of amines under green solvent. The present catalyst displayed good catalytic activity, short reaction time, higher regioselectivity, excellent yields and could be reutilized up to seven catalytic rounds with no substantial loss in its activity. The excellent properties of the catalyst are due to the dual character of acidic groups (existence of carboxyl groups on the sheet edges) and basic groups (amine groups anchored on the surface of GO). On completion of the reaction, the prepared nanocomposite could be effortlessly recovered from the reaction mixture by utilizing an external magnet, owing to the ferromagnetic property of Fe3O4.
