An electrochemical electrophilic bromination/spirocyclization of N -benzyl-acrylamides to brominated 2-azaspiro[4.5]decanes with 2-bromoethan-1-ol as the brominating reagent has been developed.
Herein, we present a metal-free, concise, and efficient protocol for the intermolecular reaction of amides (lactams) with donor-acceptor α-diazo esters to afford functionalized α-amino-α-aroylethanoates. N-Methyl-2-pyrrolidone (NMP) N,N-dimethylformamide (DMF) are employed as both reagents solvents, allowing incorporation all units into products. The is processed by ester group migration compatible broad range substrates up 50 examples.
Abstract The effects of acid activation on the chemical composition, surface area and pore structure palygorskite from Xuyi (Jiangsu, P.R. China) were investigated systematically using X-ray fluorescence (XRF) BET techniques. samples activated with HCl, H 2 SO 4 3 PO various concentrations at 80ºC for h. influences concentration type adsorption-desorption isotherms 77 K, pore-size distribution, volume studied in detail. contents most components decrease increasing except Si Ti. HCl shows a...
Abstract Density functional theory calculations have been performed to explore the potential energy surfaces of CO bond activation in CO 2 molecule by gas‐phase Nb atom and + cation for better understanding reaction mechanism second‐row metal with . The minimum‐energy path is found involve spin inversion different steps. This curve‐crossing dramatically affects energetic. present results show that insertion‐elimination along reaction. All theoretical not only support existing conclusions...
A series of new organic–inorganic nanohybrids were successfully prepared by using Congo red and heat-treated halloysite clays. The results show that an increase in calcination temperature leads to the reduction lightness ([Formula: see text]*) color hue text]*, [Formula: text]*). hybrids prepared, respectively, with 400 ∘ C treated 500 halloysites have same order HNO[Formula: text] respect acid resistance. hybrid a light can be obtained alkali treatment when calcined at higher was used as...
