Polymerization at the liquid–liquid interface has attracted much attention for synthesizing ultrathin polymer films molecular sieving. However, it remains a major challenge to conduct this process outside alkane–water since not only suffers water-caused side reactions but also is limited water-soluble monomers. Here, we report interfacial polymerization alkane/ionic liquid (IP@AILI) where ionic...

In the present study, a series of N-substituted derivatives of 2-phenylethylamine has been synthesized. The reaction of 2-phenylethylamine (1) with benzene sulfonyl chloride (2) yielded N-(2-phenylethyl) benzenesulfonamide (3), which further on treatment with alkyl/acyl halides (4a-i) in the presence of sodium hydride furnished into N-substituted sulfonamides (5a-i). These derivatives were cha...

A series of oxometallic species and metal acetylacetonates (acac) was examined as catalysts for oxidative carbonylation of styrene with benzaldehyde using t-butylhydroperoxide as the co-oxidant in warm acetonitrile. Among them, VO((acac)2 and vanadyl(IV) chloride were found to be the only catalyst class to achieve cross-coupling processes by judiciously tuning the ligand electronic attributes, ...

The title compound, C(20)H(24)O(4), was synthesized from the reaction of 2-oxo-2H-chromene-3-acyl chloride and menthol. The mean plane of the ester group and that of the four essentially planar (maximum deviation 0.0112 Å) C atoms of the chair-form cyclo-hexyl ring form dihedral angles of 43.8 (3) ° and 81.8 (1)°, respectively, with the mean plane of the coumarin ring system. In the crystal str...

The development of selective and cheap metal oxide gas sensor at ambient temperature is still a challenging idea. In this study, SnO2 surface functionalization was performed in order to obtain sensitive and selective gas sensor operated at ambient temperature. 3-aminopropyltriethoxysilane (APTES) was used as an intermediate step, followed by functionalization with molecules having acyl chloride...

A vasodepressor phospholipid fraction named Depressor-IA from a bovine brain lipid extract was analyzed by capillary gas-liquid chromatography-mass spectrometry as tert-butyldimethylsilyl derivatives after hydrolysis with phospholipase C. Results show that Depressor-IA is a mixture of 3 platelet-activating factors and 17 1-acyl analogues. Three platelet-activating factors having sn-1-0-hexadecy...

Treatment of aryl iodides with indium metal in the presence of lithium chloride leads to the formation of an organoindium reagent capable of participating in cross-coupling reactions under transition-metal catalysis. Combination with aryl halides in the presence of 5 mol % Cl2Pd(dppf) furnishes biaryl compounds in good yields; similarly, reaction with acyl halides or allylic acetates/carbonates...

1,2-Disubstituted 1,2,3,4-tetrahydrobenz[g]isoquinoline-5,10-diones are prepared for the first time through an activated Pictet-Spengler reaction of the corresponding imines of 2-(1,4-dimethoxynaphth-2-yl)ethylamine in the presence of an acyl chloride and AlCl(3) followed by an oxidation with silver(II) oxide in nitric acid. Depending on the reaction conditions the N-trichloroacetyl protecting ...

Rat liver glucokinase (EC 2.7.1.2) is inhibited specifically by the free form of palmitoyl-CoA (Ki apparent of approximately 1.8 PM) and other related long chain fatty acyl-CoAs under conditions where the micellar form of these compounds does not exist. This inhibition is instantaneous, and is immediately reversible by dilution, bovine serum albumin, and aor B-cyclodextrins. Inhibition is speci...
