Publisher SummaryThis chapter provides a brief review on uracil and its chemistry, by no means exhaustive, has pointed out by some selective but typical examples that show uracils and their derivatives possess considerable synthetic potential. In most cases, a few easy reaction steps enable the ...

A number of aromatic, cycloalkyl, and heterocyclic carbamic acid esters, thiocarbamic acid esters, and carboxylic acid esters of di- and trial-kylaminoalkyl and heterocyclic amino alcohols have been synthesized and tested for their pharmacologic and receptor binding characteristics at the nicoti...

The impact of the electrolyte additives methyl phenyl carbonate, ethyl phenyl carbonate, and diphenyl carbonate was evaluated in Li[Ni0.33Mn0.33Co0.33]O2/graphite pouch cells with or without 2% vinylene carbonate. Experiments included high precision coulometry, automated storage, electrochemical...

Synthesis and computational optimization studies have been carried out by Hartree–Fock (HF) and Density Functional Theory (DFT–B3LYP) methods with 6–31+G(d, p) basis set for 2-((E)-(2-(2-cyanoacetyl)hydrazono)methyl)-4-((E)-phenyldiazenyl)phenyl methyl carbonate (CHPMC). The stable configurat...

The vapor pressure of the pure component of methyl phenyl carbonate (MPC) was measured at temperatures ranging from 378 K to 488 K. The experimental vapor pressures could be fit well with a three-parameter Antoine equation. Isobaric vapor–liquid equilibria for binary systems (MPC + methanol and...

MoO3/SiO2 were prepared by different methods and used as heterogeneous catalysts for the liquid-phase disproportionation of methyl phenyl carbonate (MPC) to diphenyl carbonate (DPC). The characterization of XRD, FT-IR and BET showed that the preparation methods remarkably affected the structural...

A reaction coupling system of transesterification and methoxycarbonylation with methyl phenyl carbonate (MPC) as intermediate was established to efficiently prepare 1,6-hexamethylene diurethane (HDU) from 1,6-hexamethylene diamine (HDA). The feasibility of the system was explored using the therm...

Heterogeneous PbO–ZrO2 catalysts (PbZr) were first prepared by coprecipitation method, and used to catalyze the liquid-phase disproportionation reaction of methyl phenyl carbonate (MPC) to synthesize diphenyl carbonate (DPC). PbZr with PbO loading of 15.2 wt% (15.2PbZr) exhibited the best catal...

The disproportionation of methyl phenyl carbonate (MPC) to synthesize diphenyl carbonate (DPC) catalyzed by organo-titanium compounds with different coordination groups was systematically investigated. The results of the molecular structure analysis, the catalytic performance evaluation and the ...

The effectiveness of methyl phenyl carbonate and diphenyl carbonate as electrolyte additives either singly or in combination with methylene methyl disulfonate and tris(-trimethyl-silyl)-phosphite has been systematically investigated in LiNi0.8Mn0.1Co0.1O2/graphite pouch cells. Experiments conduc...

Despite apparent similarity, two isotopomers of acetonitrile (ACN-h3 and ACN-d3) show unexpected differences in their structural and dynamic properties. These differences cannot be fully understood within the usual isotope effect and therefore called as unresolved casus. Sensing the solvent prop...

Ethyl 4 - (9-ethyl-9H-carbazol-3-yl) – 2 – methyl - 5- oxo - 4, 5 - dihydro-1H-indeno[1,2-b]pyridine-3-carboxylate (ECPC) was prepared by one pot multi component reaction of 9-ethyl-9H-carbazole-3-carbaldehyde, indane-1,3-dione, ethyl acetoacetate and ammonium acetate in the presence few drops...

The base-mediated reaction of enantiomerically pure α-sulfinylketimine (+)-1 with (E)-α,β-disubstituted propenoate esters afforded 3,4-disubstituted-5-(p-tolylsulfinyl)-5,6-dehydropiperidin-2-ones 9α-13α and 14 with high or complete diastereoselectivity. A sole diastereomer of the four poss...

The X-ray structural characterization of ethyl 5-cyano-1,6-dihydro-2-isopropyl-6-oxo-3-pyridine carboxylate is reported. Its solid state conformation has been compared with that of ethyl 2-methyl- and 2-tert-butyl-5-cyano-1,6-dihydro-6-oxo-3-pyridine carboxylate and with the results of a quantum...

Compound 2-chloro-4-(methoxymethyl)-6-methyl-5-nitropyridine-3-carbonitrile (2) has been obtained from 4-(methoxymethyl)-6-methyl-5-nitro-2-oxo-1,2-dihydropyridine-3-carbonitrile (1) by novel protocol using Vilsmeier–Haack chlorination and its solid state structure was analyzed using X-ray anal...

ZusammenfassungDie lineare Vorstufe H-(D-Val-L-Lac-L-Val-D-Hyv-)3OH* des Cyclododecadepsipeptides Valinomycin wurde auf drei parallelen Wegen aufgebaut: (1) in homogener Phase durch stufenweise N-terminale Verlängerung von H-L-Val-D-Hyv-OBzl mit Boc-Aminoacyl-hydroxysäuren; (2) nach demselben Pr...

The reductive amination of 2,5-hexanedione and 2,6-heptanedione with ammonia and primary amines in the presence of hydride regents afforded 2,5-dimethylpyrrolidines and 2,6-dimethylpiperidines with variable diastercoselectivity, as the cis/trans ratio was affected by the size of the ring formed ...

Organic sulfonyl fluorides are of interest owing to their insecticidal, germicidal and enzyme inhibitory properties. In the current work, synthesis of p-toluenesufonyl fluoride was accomplished by reacting p-toluenesulfonyl chloride with solid potassium fluoride using PEG-400 as a catalyst under...

A series of novel p-toluenesulfonyl-hydrazinothiazoles and hydrazino-bis-thiazoles derivatives (2a–f, 3a–f and 5–8) were synthesized by initial condensation of p-toluenesulfonylthiosemicarbazide 1 with a series of α-halogenocarbonyls in acetone or dimethylformamide (DMF)/acetone, mixture. Al...

A silver-catalyzed reaction of 2-alkynylbenzaldoxime with phenol promoted by p-toluenesulfonyl chloride leads to 1-aroxyisoquinolines in good yields. The presence of p-toluenesulfonyl chloride as an activator is essential for the successful transformation.
