Yamasaki, Ryu published the artcileConformational Switch of Benzanilide Derivative Induced by Acid; Effect of Pentafluorobenzoyl Group, Formula: C8H11NO, the main research area is benzanilide derivative conformational switch protonation pentafluorobenzoyl group effect.

Amide-based mol. switches had its limitation on structural diversities. In this work, we designed and synthesized a series of pentafluorobenzoyl-based benzanilide compounds The conformational ratio of these compounds in solution was correlated linearly with Hammett’s σp value of the substituent on the anilide ring, reflecting the repulsive interaction between the carbonyl group and the electron-rich aryl group. The addition of acid into the solution of 6, bearing pentafluorobenzoyl group, switched the stable amide conformation. In addition, the sizeable rotational barrier of 6 induced by the pentafluorobenzoyl moiety enabled us to monitor the conformational transition by means of 1H NMR spectroscopy.

Cao, Qiang published the artcileCovalent organic framework-supported Zn single atom catalyst for highly efficient N-formylation of amines with CO2 under mild conditions, HPLC of Formula: 5961-59-1, the main research area is covalent organic framework supported zinc catalyst formylation amine CO2.

Transformation of CO2 into value-added chems. with efficient and recyclable catalyst is an effective way to reduce carbon emissions. It is valuable to develop an efficient catalyst that can promote the N-formylation reaction under mild conditions with a high activity and excellent recyclability. Single atom catalysts (SACs) possess ultimate atom utilization efficiency and outstanding catalytic performance. Herein, we synthesize Zn SACs (Zn-TpPa) anchored on a COF (TpPa-1) using a facile solution method. Catalyzed by Zn-TpPa, CO2 and N-methylamine are transformed into N-methylformanilide under mild reaction conditions with a TOF of 17,155 h-1, which is the highest among all reported recyclable Zn-based catalysts. Zn-TpPa can also catalyze N-formylation of many other amines with excellent yields. The higher reactivity was attributable to the well-dispersed Zn active sites on COF and outstanding adsorption of CO2 owing to high surface area of COF. Our research provides a facile method for constructing SACs as well as an effective pathway for CO2 transformation and environmental protection.

Viayna, Antonio published the artcileHolistic approach to anti-knock agents: A high-throughput screening of aniline-like compounds, Synthetic Route of 5961-59-1, the main research area is aniline compound antiknock fuel additive library screening.

The increasing concerns about greenhouse gas emissions are encouraging the search for efficient combustion technologies for transportation. A valuable strategy consists of tailoring the properties of fuels through addition of additives that might increase the octane number subject to the classification, labeling and packaging regulation of fuel quality. In this context, we present an integrated approach involving a high-throughput screening that relies on selected physicochem. factors of aniline-like compounds, measurements of structural resemblance and susceptibility to participate in chem. reactions with radical species, in conjunction with production viability as well as environmental and toxicol. risks. This process led to a final set of representative compounds that were chosen to explore their behavior as anti-knock additives. The suitability of these compounds was determined through assays performed to determine the impact on fuel volatility and RON booster efficiency in conjunction with a critical assessment of their eco/toxicol. risk estimated by means of a safety index. This holistic strategy led to the identification of N-methyl-p-anisidine, N’,N’-diethyl-2-methyl-p-phenylenediamine and N-nitroso-diphenylamine as promising anti-knock additives. This approach is proposed as an alternative strategy to the unsupervised exptl. screening of fuel additives.

Simple, efficient and transition-metal free method for the preparation of valuable and sterically hindered 3,3-disubstituted oxindoles via polar-radical crossover of ketene derived amide enolates. Various easily accessible N-alkyl and N-arylanilines are added to disubstituted ketenes and the resulting amide enolates undergo upon single electron transfer oxidation a homolytic aromatic substitution (HAS) to provided 3,3-disubstituted oxindoles in good to excellent yields. A variety of substituted anilines and a 3-amino pyridine engage in this oxidative formal [3 + 2] cycloaddition and cyclic ketenes provided spirooxindoles.
