3-Aryl-amido/imido-methyl-4-hydroxy-phenyl-acetophenones (I) were prepared in excellent yields by condensing equilmolar amounts or p-hydroxy acetophenones and aryl-amido/imido-alcohols in the presence of conc. H2SO4. Reaction of (I) with semicarbazide, hydro-chloride in ethanol afforded 3-Aryl-amido/imido-methyl-4-hydroxyphenyl-acetophenone-semicarbazones (II) in the yields ranging from 60-70%....

The chemical composition of the essential oils obtained from aerial parts of Scutellaria immaculata Nevski ex Juz., Scutellaria ramosissima M. Pop. and Scutellaria schachristanica Juz. (Lamiaceae) growing wild in Uzbekistan was analysed by GC and GC-MS. The main constituents of the essential oils from S. immaculata were acetophenone (30.39%), eugenol (20.61%), thymol (10.04%) and linalool (6.92...

We investigate the chemical and structural configuration of acetophenone on Si(0 0 1) using synchrotron radiation core-level spectroscopy techniques and density functional theory calculations. Samples were prepared by vapour phase dosing of clean Si(0 0 1) surfaces with acetophenone in ultrahigh vacuum. Near edge x-ray absorption fine structure spectroscopy and photoelectron spectroscopy measur...

A Vilsmeier salt supported on solid phase was prepared using piperazine bound to Merrifield resin. Piperazine was selected because it contains two secondary amines: one of the amines is protected upon binding to the resin, and the second was formylated to give resin-1-N-piperazine-4-N-carboxaldehyde (9). Activation of the formamide with either bis(trichloromethyl)carbonate (BTC) or POCl(3) affo...

THE TITLE COMPOUND (SYSTEMATIC NAME 4-{3-[2-aza-tricyclo-[9.4.0.0(3,8)]penta-deca-1(15),3,5,7,11,13-hexaen-2-yl]prop-yl}-1-(2-hy-droxy-eth-yl)piperazine-1,4-diium dichloride), C(23)H(31)N(3)O(+)·2Cl(-), is the dihydro-chloride of a piperazine derivative bearing a bulky 3-(5H-dibenz[b,f]azepin-5-yl)propyl substituent. Protonation took place on both N atoms of the piperazine unit. The diaza-cyclo...

In the title compound, C(18)H(18)F(2)N(2)O(3)S, the piperazine ring adopts a chair conformation. The dihedral angle between the sulfonyl-bound benzene ring and the best fit plane throught the six non-H atoms of the piperazine ring is 69.4 (2)°, while those between the fluoro-benzene and sulfonyl rings and the fluoro-benzene and piperazine rings are 30.97 (2) and 75.98 (2)°, respectively. In the...
