Abstract:
Ring opening of donor–acceptor cyclopropanes with various N-nucleophiles provides a simple approach to 1,3-functionalized compounds that are useful building blocks in organic synthesis, especially in assembling various N-heterocycles, including natural products. In this review, ring-opening reactions of donor–acceptor cyclopropanes with amines, amides, hydrazines, N-heterocycles, nitriles, and the azide ion are summarized.1 Introduction2 Ring Opening with Amines3 Ring Opening with Amines Accompanied by Secondary Processes Involving the N-Center3.1 Reactions of Cyclopropane-1,1-diesters with Pr

Abstract. Amines and amides are important atmospheric organic-nitrogen compounds but high time resolution, highly sensitive, and simultaneous ambient measurements of these species are rather sparse. Here, we present the development of a high-resolution time-of-flight chemical ionization mass spectrometer (HR-ToF-CIMS) method, utilizing protonated ethanol as reagent ions to simultaneously detect atmospheric gaseous amines (C1 to C6) and amides (C1 to C6). This method possesses sensitivities of 5.6–19.4 Hz pptv−1 for amines and 3.8–38.0 Hz pptv−1 for amides under total reagent ion signals of ∼ 0

AbstractAmines and amides, as N-containing compounds, are ubiquitous in pharmaceutically-active scaffolds, natural products, agrochemicals, and peptides. Amides in nature bear a key responsibility for imparting three-dimensional structure, such as in proteins. Structural modifications to amines and amides, especially at their positions α to N, bring about profound changes in biological activity oftentimes leading to more desirable pharmacological profiles of small drug molecules.

Eleven rounds of directed evolution completely altered the enzyme’s specificity and successfully created amination activity.

The intercalation of primary, secondary, tertiary, and aromatic amines into layered TiOCl have been investigated by a variety of methods.

A key step for intercalation of amines into host TiOCl is proposed to be a coordination via nitrogen lone electron pair to Ti$\sp{3+}$ metal centres. Subsequent substitution of the interlayer chloride ions of TiOCl by the amine molecules is strongly dependent on the properties of the organic compounds and their ability to form ammonium salts.

In view of the rising amounts of greenhouse gases in the atmosphere, preventing CO2 emissions has become increasingly important. The combustion of fossil fuels for energy production and transportation is a large contributor to the problem. One of the ways to reduce the amounts of CO2 being released from combustion is carbon capture and storage (CCS). Post-combustion is the capturing method which has been deemed the easiest to apply to existing power plants in a short period of time. Absorption of CO2 by MEA is the most common method used in post-combustion carbon capture, but there are still

Abstract Amine solutions have been widely used to remove acid gases at gas treatment units found in gas plants, refineries and other facilities. Corrosion is always a challenge for these units, particularly for carbon steel equipment or piping that are processing hot amines. Amines are noncorrosive by nature. However, once acid gases are dissolved in amines, they act as strong electrolytes, which significantly increase the susceptibly of carbon steel components to corrode. Temperature, acid gas loading, velocity, and degradation products are the primary factors that influence amine corrosion.
