Synthesize of large-sized porous carbon spheres with controllable N-content via spray-drying and photo-induced RAFT polymerization

A method combined spray-drying process with light-induced reversible addition fragmentation chain transfer (RAFT) polymerization was used to synthesize N-doped carbon spheres (N-CS). Firstly, the common used carbon precursor phenolic resin which called Resol was modified with a chain transfer agent (CTA). Then, the mixed ethanol solution of CTA modified Resol, F127, TEOS, and HCl was used as starting material. After a typical spray-drying process, uniformed and discrete composite spheres in regular size (70 mum) were obtained. The RAFT polymerization of acrylonitrile was initiated under the irradiation of blue LED at the surface of spheres. Through such manner, controlled amount of polyacrylonitrile was introduced onto the surface of carbon sphere. After calcination at 900 C and etching, the obtained porous N-CS (60 mum) showed controllable total N content up to 10.8 wt%, tunable high surface area up to 1130 m2/g and good CO2 absorptivity which can up to 4.34 mmol/g at 273 K and 4.13 mmol/g at 298 K at 1.0 bar.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. COA of Formula: C12H28BrN, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1941-30-6, in my other articles.

Novel catalytic hydrogenolysis of trimethylsilyl enol ethers by the use of an acidic ruthenium dihydrogen complex

The heterolytic cleavage of H2 is the key to the novel catalytic hydrogenolysis of trimethylsilyl enol ethers catalyzed by [RuCl(eta2- H2)(dppe)2]OTf (dppe = 1,2-bis(diphenylphosphanyl)ethane, OTf = trifluoromethanesulfonate), which results in the formation of a ketone and Me3SiH (see scheme). In addition, the stoichiometric, ruthenium-assisted protonation of a prochiral lithium enolate with H2 gave a chiral ketone with high enantioselectivity (up to 75 % ee).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Related Products of 2926-30-9, you can also check out more blogs about2926-30-9

Ag-catalyzed C-H/C-C bond functionalization

Silver, known and utilized since ancient times, is a coinage metal, which has been widely used for various organic transformations in the past few decades. Currently, the silver-catalyzed reaction is one of the frontier areas in organic chemistry, and the progress of research in this field is very rapid. Compared with other transition metals, silver has long been believed to have low catalytic efficiency, and most commonly, it is used as either a cocatalyst or a Lewis acid. Interestingly, the discovery of Ag-catalysis has been significantly improved in recent years. Especially, Ag(i) has been demonstrated as an important and versatile catalyst for a variety of organic transformations. However, so far, there has been no systematic review on Ag-catalyzed C-H/C-C bond functionalization. In this review, we will focus on the development of Ag-catalyzed C-H/C-C bond functionalization and the corresponding mechanism.

Fe-Catalyzed Reductive Couplings of Terminal (Hetero)Aryl Alkenes and Alkyl Halides under Aqueous Micellar Conditions

The combination of a vinyl-substituted aromatic or heteroaromatic and an alkyl bromide or iodide leads, in the presence of Zn and a catalytic amount of an Fe(II) salt, to a net reductive coupling. The new C-C bond is regiospecifically formed at rt at the beta-site of the alkene. The coupling only occurs in an aqueous micellar medium, where a radical process is likely, supported by several control experiments. A mechanism based on these data is proposed.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 1660-93-1 is helpful to your research. Related Products of 1660-93-1

Synthesis of new sulfonium ylides bearing the chiral diazaphospholidine group as reagents for asymmetric cyclopropanation

Sulfonium ylides derived from chiral N,N?-substituted (benzyl, isopropyl, neopentyl) phosphonamides were prepared by reacting appropriate chiral diamidophosphites with potassium hydride and chloromethyl methyl sulfide, and then with methyl iodide in the presence AgBF4 to give the corresponding sulfonium salts in high yields. One of them was analyzed by X-ray crystallography. The salts upon treatment with different bases (LithiumDiisopropylAmine, BuLi, K2CO3) were converted in situ into ylides, which were reacted with activated olefins to produce phosphonocyclopropanes as a mixture of two diastereoisomers with moderate-to-high diastereoselectivities.

Phase transfer catalysis: Effect of cationic surfactants on the free radical polymerization of methylmethacrylate

The effect of cationic surfactants, decyltrimethylammonium bromide (DTAB), dodecyltrimethylammonium bromide (DDTAB) and tetradecyltrimethylammonium bromide (TDTAB), has been studied as phase transfer catalysts (PTCs) on the free radical polymerization of methylmethacrylate (MMA) using potassium peroxydisulfate (PDS, K2S2O8) in toluene-water biphase system. Of the three PTCs in their respective critical micellar concentration (CMC) and in common concentration, the TDTAB show comparatively high rate of polymerization (Rp), 7.76 ¡Á 10-5 mol.L-1.S-1, at the lowest reaction time of 30 min in its concentration of 2 ¡Á 10-2 mol.L-1. Detailed kinetic study of polymerization of MMA has been carried out using TDTAB at a fixed time of 30 min by varying [MMA], [K2S2O8], [TDTAB] and temperature. Based on the kinetic results, the free energy of activation has been calculated, and a suitable mechanism and rate law has been proposed.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Formula: C17H38BrN, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 1119-97-7
