Check Digit Verification of cas no

The CAS Registry Mumber 151451-82-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,4,5 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 151451-82:
(8*1)+(7*5)+(6*1)+(5*4)+(4*5)+(3*1)+(2*8)+(1*2)=110
110 % 10 = 0
So 151451-82-0 is a valid CAS Registry Number.

A palladacyclic N-heterocyclic carbene system used to probe the donating abilities of monoanionic chelators

Yan, Xuechao,Feng, Rui,Yan, Chunhui,Lei, Peng,Guo, Shuai,Huynh, Han Vinh

, p. 7830 - 7838 (2018)

A series of NHC-containing [C^N]- or [C^C′]-type palladacyclic complexes of the general formula [PdBr(iPr2-bimy)(L^X)] (5-8, 11, 12, iPr2-bimy = 1,3-diisopropylbenzimidazolin-2-ylidene) have been synthesized and fully characterized. Using these complexes, the donating abilities of monoanionic chelators were probed for the first time. The [C^N]-type palladacycles 5-8 were prepared from acetato-bridged dipalladium complexes [Pd(μ-CH3COO)(C^N)]2 (1-4) and iPr2-bimy·H+Br-as precursors. In the case of the [C^C′]-type NHC palladacycles (11, 12), the hetero-bis(NHC) complexes trans-[PdBr2(iPr2-bimy)(trz)] (8, 9, trz = 1,2,3-triazolin-5-ylidene) containing the iPr2-bimy probe were first prepared followed by acetate-assisted cyclopalladations. The 13Ccarbene NMR signals of the iPr2-bimy ligands in all complexes (i.e. HEP and HEP2 values) are found to rationally reflect the donating abilities of the incorporated trz or [L^X]-type chelators with the exception of the Bzpy ligand (Bzpy = 2-(2-pyridinylmethyl)phenyl-C,N). This has been attributed to its larger bite angle, the resulting varied coordination geometry and the lack of electronic delocalization between the two donor units. The donicities of [L^X]-type chelators studied in this work were found to surpass those of all other bidentate ligands evaluated by HEP2 thus far.

Silica immobilized copper N-heterocyclic carbene: An effective route to 1,2,3-triazoles via azide-alkyne cycloaddition and multicomponent click reaction

Garg, Anirban,Borah, Nobomi,Sultana, Jasmin,Kulshrestha, Akshay,Kumar, Arvind,Sarma, Diganta

, (2021/06/11)

A new silica supported copper N-heterocyclic carbene (Cu-NHC@SiO2) complex is prepared and characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS) analyses. This complex is an efficient and easily retrievable catalyst for 1,2,3-triazole synthesis through direct azide-alkyne cycloaddition reaction as well as one-pot reaction using arylboronic acids. This catalytic system is also suitable for synthesis of 4-aryl-NH-1,2,3-triazoles from diverse benzaldehydes. Further, the catalyst can efficiently be recycled up to fifth cycle for all the three methods of 1,2,3-triazole synthesis through direct azide-alkyne cycloaddition and multi-component reactions.

Using Small Molecules to Enhance P450 OleT Enzyme Activity in Situ

Zhang, Libo,Ma, Dumei,Yin, Yingwu,Wang, Qian

supporting information, p. 8940 - 8945 (2021/05/28)

Cytochrome P450 OleT is a fatty acid decarboxylase that catalyzes the production of olefins with biofuel and synthetic applications. However, the relatively sluggish catalytic efficiency of the enzyme limits its applications. Here, we report the application of a novel class of benzene containing small molecules to improve the OleT activity. The UV-Vis spectroscopy study and molecular docking results confirmed the high proximity of the small molecules to the heme group of OleT. Up to 6-fold increase of product yield has been achieved in the small molecule-modulated enzymatic reactions. Our work thus sheds the light to the application of small molecules to increase the OleT catalytic efficiency, which could be potentially used for future olefin productions.

A ferrocene functionalized Schiff base containing Cu(ii) complex: Synthesis, characterization and parts-per-million level catalysis for azide alkyne cycloaddition

Atom economy is one of the major factors in developing catalysis chemistry. Using the minimum amount of catalyst to obtain the maximum product yield is of the utmost priority in catalysis, which drives us to use parts-per-million (ppm) levels of catalyst

Polysaccharide-based superporous hydrogel embedded with copper nanoparticles: A green and versatile catalyst for the synthesis of 1,2,3-triazoles

Souza, Jaqueline F.,Costa, Gabriel P.,Luque, Rafael,Alves, Diego,Fajardo, André R.

, p. 136 - 145 (2019/01/10)

In this contribution, we a report a facile synthesis and stabilization of copper nanoparticles (CuNPs) in a superporous hydrogel based on chitosan (Cs) and poly(vinyl alcohol) (PVA). The functional groups of Cs and PVA stabilized the CuNPs and, as a result, several properties (e.g. thermal, morphological and liquid uptake) of the final materials exhibited remarkable improvements in terms of stability and catalytic activity. The metallic nature of CuNPs was confirmed by XRD and XPS analyses. From the XRD data, the Cu nanoparticle size was estimated to range from 3 to 7 nm. Moreover, EDS mapping analysis revealed that the CuNPs are homogeneously distributed throughout the hydrogel surface. The Cs/PVA-CuNP hydrogel was found to be an excellent catalyst for the synthesis of 1,2,3-triazoles using phenyl azide and phenylacetylene as model substrates under mild optimized conditions (>90% yield). Reuse studies revealed that this original CuNP-containing catalyst can be employed in at least 5 consecutive cycloaddition reactions without demonstrating a clear loss of efficiency. Moreover, the copper leaching from the hydrogel matrix was negligible during these consecutive reactions under the investigated conditions. The Cs/PVA-CuNP hydrogel could also efficiently catalyze cycloaddition reactions involving different substituted azide and alkyne precursors.

Mono- and dinuclear palladium(II) complexes incorporating 1,2,3-triazole-derived mesoionic carbenes: syntheses, solid-state structures and catalytic applications

Zhang, Xin,Yan, Xuechao,Zhang, Bo,Wang, Ran,Guo, Shuai,Peng, Shiyong

, p. 39 - 48 (2018/08/06)

Two 1,2,3-triazole-derived monocationic salts 3 and 4 bearing N-aryl wingtips were prepared using copper-catalyzed “click” reactions followed by alkylations with iodomethane. Employing a silver–carbene transfer method, two dinuclear palladium(II) complexes of triazolin-5-ylidenes (5/6) were obtained, the former of which has been reported previously. Bridge-cleavage reaction of 5 as a representative with PPh3 yielded cis-configured mesoionic carbene/phosphine hybrid complex cis-7 and homoleptic bis(phosphine) complex 8, suggesting the presence of a ligand exchange process. In contrast, bridge breakages of 5/6 with pyridine cleanly afforded PEPPSI-type complexes 9 and 10 in near quantitative yields. Finally, all complexes were exploited to catalyze Mizoroki–Heck coupling reactions with aryl bromides as the substrates, and PEPPSI-type complex 9 was found to be the best performer generally giving good to excellent yields.
