A simple one-pot preparation of N-allenyl amides, ureas, carbamates and sulfonamides using a DMSO/tBuOK protocol

A one-pot transformation of amides, ureas, carbamates and sulfonamides into synthetically useful N-allenyl analogues using a tBuOK/DMSO protocol is reported. The procedure is experimentally simple and robust, and provides N-allenyl analogues, commonly used within the literature, in yields comparable to the benchmark two-step approach.

Carbon dioxide induced degradation of diethanolamine during absorption and desorption processes

Alkanolamines are widely used in the purification of the sour gas sweetening process. During the sour gas absorption process, CO2 significantly degrades the amine solvent and creates enormous problems for plant operation. In this work, CO2 induced degradation of aqueous diethanolamine (DEA) solution was conducted in a 1.25 L jacketed glass reactor that functioned as an absorber and stripper at atmospheric conditions. Pure CO2 was bubbled through the reactor until the solution became saturated. In this study, the concentrations of DEA used were in the range of concentrations between 2 mol¡¤L? 1 and 4 mol¡¤L? 1. In the degradation experiment, six generic cycles were conducted for each run. Each cycle was configured with the absorption and desorption of carbon dioxide at 55 C and 100 C, respectively. Samples were collected after a predetermined experimental time and analyzed by ion chromatography (IC) to identify unknown ionic degradation products (DGPs). In the IC analysis, three different columns were used for anion, cation and ion exclusion systems, which are Metrosep A Supp 5 150/4.0, Metrosep C Supp 4 150/4.0 and Metrosep Organic Acids, respectively. The major identified DGPs of D01DEA2M, D02DEA3M, and D03DEA4M are nitrite, acetate and ammonium. Phosphate product was found in the degraded amine samples which might be due to the contamination of water or chromatographic system.

Quality Control of Oxazolidin-2-one, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 497-25-6, in my other articles.

pH-sensitive assembly of light-harvesting dendrimer zinc porphyrin bearing peripheral groups of primary amine with poly(ethylene glycol)-b-poly(aspartic acid) in aqueous solution

The light-harvesting dendrimer zinc porphyrin [NH2CH2CH2NHCO]32DPZn, a potential photosensitizer in photodynamic therapy, was synthesized and successfully assembled with poly(ethylene glycol)-b-poly(aspartic acid) to form micelles in PBS buffer (10 mM) following the concept of polyion complex micelle. The coupling reaction between the [CO2H]32DPZn and N-trifluoroacetylethylene-l,2-diamine using the DCC/HOBt method afforded the protected dendrimer [CF3CONHCH2CH2NHCO]32DPZn, which was then mildly hydrolyzed to remove all the trifluoroacetyl protecting groups. Light-scattering measurements showed that the [NH2CH2CH2NHCO]32DPZn has the ability to assemble with poly(ethylene glycol)-b-poly(aspartic acid) to form a spherical micelle with a diameter of about 55 nm, having a narrow size polydispersity in PBS. The micelles were stable both in size and composition up to a 0.90 M (NaCl) salt concentration. The high salt stability is associated with a hydrogen-bonding network formed in the micellar core among the amide groups of the dendrimers and those of poly(aspartic acid) moieties, which could be destroyed by urea, a typical hydrogen-bonding cleaver. Furthermore, the pH range for the stable micelles in physiological saline (0.15 M NaCl) is from 6.2 to 7.4, suggesting the potential of the pH-triggered release of the entrapped dendrimers in the acidic pH environment (pH ? 5.0) of the intracellular endosomal compartment.
