Phase-transfer catalysis for synthesis of ethyl 2-(4-nitrophenoxy)acetate under sonication- kinetic aspects
Ultrasound assisted phase-transfer catalyzed preparation of ethyl 2-(4-nitrophenoxy)acetate from the corresponding p-nitrophenol and ethyl 2-bromoacetate using the mild solid base, anhydrous potassium carbonate, under very mild conditions is reported. The solid-liquid reactions were performed in a batch reactor equipped with reflux condenser, and ultrasonic irradiations were introduced using an...

Crystals of the title compound, C(22)H(29)NO(5)·C(4)H(8)O(2), {[systematic name: (2R,3R,5R,5aS,6R,8aR,9S)-(5Z)-5-[3-butyl-tetra-hydro-6-methyl-2,5-methano-4,3,8a-[1]propan-yl[3]yl-idene-furo[3,2-f][1,4]oxazepin-7(5H)-yl-idene]-4-meth-oxy-3-methyl-furan-2(5H)-one ethyl acetate solvate} were isolated from the root extracts of Stemona aphylla (Stemonaceae). The structure closely resembles those of...
متن کاملIsobaric vapor-Liquid Equilibrium of Ethyl-Acetate+ 2-Propanol and Ethyl Acetate+ Ethanol Mixtures at 84.8 kPa
Accurate vapor-liquid equilibrium data have been obtained for ethyl acetate + 2-propanol and ethyl acetate + ethanol mixtures at 84.8 kPa, and the results are discussed thermodynamically. The vapor-liquid equilibrium data are correlated with redlich-Kister, Margules, Van-Laar and Ortega, equations the parameters and standard deviation of which are calculated and reported. The best correlati...
متن کاملEthyl 2-(2,3,4,5,6-Pentabromophenyl)acetate
The title compound PBPEA, C(10)H(7)Br(5)O(2), has its ethyl acetate portion nearly orthogonal to the benzene ring, with a C-C-C-C torsion angle of 88.3 (5)°. The packing involves an inter-molecular contact with a Br⋯Br distance of 3.491 (1) Å, having C-Br⋯Br angles of 173.4 (2) and 106.0 (2)°. The crystal studied was an inversion twin.
متن کاملEthyl 2-(3-benzoylthioureido)acetate
The title compound, C(12)H(14)N(2)O(3)S, adopts a cis-trans geometry of the thio-urea group and is stabilized by intra-molecular hydrogen bonds between the carbonyl O atoms and the H atom of the thio-amide group and by a C-H⋯S interaction. Mol-ecules are linked by two inter-molecular hydrogen bonds (C-H⋯O and N-H⋯O), forming a one-dimensional chain parallel to the c axis.
