Comprehensive monitoring of MEA degradation in a post-combustion CO2 capture pilot plant with identification of novel degradation products in gaseous effluents

A pilot plant campaign was performed to study MEA degradation in CO2 capture conditions and anticipate potential degradation products emissions to the atmosphere in industrial case. Aqueous 30% wt MEA was cycled between absorption and regeneration steps during 1700 h in the presence of a synthetic flue gas containing 81% of N2, 14% of CO2, 5% of O2, 97 ppm of NO, 9 ppm of SO2 and 5 ppm of NO2. Specific methods (sampling, sample conditioning and analysis) were developed to improve degradation products identification and to provide a quantification of targeted compounds in liquid phase and above all in absorber and stripper gas effluents. Especially, trace elements were detected in liquid phase thanks to Head Space-Solid Phase MicroExtraction (HS-SPME) and liquid-liquid extraction with ChemElut cartridges and in gas phase thanks to adsorbent tubes of different type: Sep-Pak for aldehydes and ketones, Orbo 60 for N-nitrosodimethylamine, Tenax and active charcoal for non-specific adsorption. 32 degradation products were identified in liquid phase and 38 in gas phase, 17 of which for the first time, especially derivatives of pyridine and oxazolidine, 1H-pyrrole and a new nitrosamine, the N-nitroso-2-methyl-oxazolidine.

Broadly Applicable Ytterbium-Catalyzed Esterification, Hydrolysis, and Amidation of Imides

An efficient, broadly applicable, operationally simple, and divergent process for the transformation of imides into a range of carboxylic acid derivatives under mild conditions is reported. By simply using catalytic amounts of ytterbium(III) triflate as a Lewis acid promoter in the presence of alcohols, water, amines, or N,O-dimethylhydroxylamine, a broad range of imides is smoothly and readily converted to the corresponding esters, carboxylic acids, amides, and Weinreb amides in good yields. This method notably enables an easy cleavage of oxazolidinone-based auxiliaries.

The effect of fluoromethyl groups on the diastereoselectivity in the electrophilic alkylation is described. In particular, the electrophilic alkylation of enolates with a trifluoromethyl group was proceeded with highly diastereofacial selectivity based on the steric and/or electrostatic effect of substituent with strong electron withdrawing.

Gold-catalyzed heterocyclic syntheses through alpha-imino gold carbene complexes as intermediates

Gold carbene complexes have been recognized as common intermediates in gold-catalyzed organic syntheses. In this field, alpha-imino gold carbene complexes, in the last few years, have emerged as valuable intermediates toward the synthesis of N-heterocycles. This review is dedicated toward formulating a comprehensive compilation of the different methodologies for heterocyclic synthesis, postulating the participation of alpha-imino gold carbene complexes as intermediates. In addition to the scarce examples involving the direct formation of alpha-imino diazo compounds from gold decomposition, the use of nitrogenated nucleophiles, through an initial attack on gold-activated alkynes followed by gold retrodonation and expulsion of a leaving group, constitutes the most commonly employed strategy for achieving this target. This review has been divided into different sections as follows according to the type of N-nucleophile used: azides, aza-ylides, 2H-azirines, isoxazoles and their derivatives, indazoles, and triazapentalenes. A large number of heterocycles, ranging from five- to seven-membered rings, have been efficiently synthesized following this methodology.

Probing the influence of protecting groups on the anomeric equilibrium in sialic acid glycosides with the persistent radical effect

A method for the investigation of the influence of protecting groups on the anomeric equilibrium in the sialic acid glycosides has been developed on the basis of the equilibration of O-sialyl hydroxylamines by reversible homolytic scission of the glycosidic bond following the dictates of the Fischer-Ingold persistent radical effect. It is found that a trans-fused 4O,5N-oxazolidinone group stabilizes the equatorial glycoside, i.e., reduces the anomeric effect, when compared to the 4O,5N-diacetyl protected systems. This effect is discussed in terms of the powerful electron-withdrawing nature of the oxazolidinone system, which in turn is a function of its strong dipole moment in the mean plane of the pyranose ring system. The new equilibration method displays a small solvent effect and is most pronounced in less polar media consistent with the anomeric effect in general. The unusual (for anomeric radicals) poor kinetic selectivity of anomeric sialyl radicals is discussed in terms of the planar pi-type structure of these radicals and of competing 1,3-diaxial interactions in the diastereomeric transition states for trapping on the alpha- and beta-faces of the radical.
