The title compound, C(8)H(7)BrO, is a halogenated derivative of acetophenone. The mol-ecule shows noncrystallographic C(s) symmetry. The intra-cyclic C-C-C angles cover the range 118.8 (2)-120.4 (3)°. In the crystal structure, C-H⋯O contacts connect the mol-ecules into undulating sheets perpendicular to the crystallographic c axis.

During the Mediterranean Intensive Oxidant Study (MINOS) campaign in August 2001 gas-phase organic compounds were measured using comprehensive twodimensional gas chromatography (GC×GC) at the Finokalia ground station, Crete. In this paper, C7−C11 aromatic and n-alkane measurements are presented and interpreted. The mean mixing ratios of the hydrocarbons varied from 1±1 pptv (i-propylbenzene) to...

Olfactory sensitivity of the southern pine beetle, Dendroctonus frontalis Zimmermann, to compounds isolated from the mid/hindguts of newly emerged conspecific adults was assayed with coupled gas chromatography-electroantennographic detection. All previously reported pheromones for D. frontalis plus eight additional compounds (fenchyl alcohol, myrtenal, cis-verbenol, trans-pinocarveol, acetophen...

The title compound, C(29)H(26)O(4), is essentially planar in the acetophenone portion that includes both the hy-droxy and a benz-yloxy O atoms, with an r.m.s. deviation of 0.0311 Å. The other two substituents inter-sect the plane at 70.45 (3) and 59.55 (4)°. In the molecule there is an intramolecular O-H⋯O hydrogen bond. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, as well as ...

Recent work from our group (Lozovoy, V. V.; Zhu, X.; Gunaratne, T. C.; Harris, D. A.; Shane, J. C.; Dantus, M. J. Phys. Chem. A2008, 112, 3789) using shaped nonresonant femtosecond pulses to ionize and fragment polyatomic molecules indicated that pulse duration is the most important parameter for controlling the relative yield of different fragment ions. Here we explore the time-resolved dynami...

A series of copper complexes were prepared from N4 – substituted Schiff base ligands having structure [Cu (L)2] Cl2 ; where L= p-methoxy benzylidene ethylene diammine, p-nitro benzylidene ethylene diammine, pchloro acetophenone ethylene diammine, p-methoxy acetophenone ethylene diammine, p-nitro acetophenone ethylene diammine. All copper complexes were characterized by various physicochemical t...

zogenes are differentiated cells capable of the biosynthesis of secondary metabolites. Hairy roots also have a high rate of proliferation. They are therefore expected to become widely used culture systems for the production of useful secondary metabolites and for studies on the production of biologically active compounds and transformation of organic substrates. We reported the production of a ...

The photophysics and photochemistry of molecules with complex electronic structures, such as aromatic carbonyls, involve dark structures of radiationless processes. With ultrafast electron diffraction (UED) of isolated molecular beams it is possible to determine these transient structures, and in this contribution we examine the nature of structural dynamics in two systems, benzaldehyde and ace...

An efficient and practical catalytic system for the anti-Markovnikov ruthenium-catalyzed hydroarylation of styrenes with acetophenone, allowing a straightforward access to bibenzyl backbones, is described for the first time: this process, involving regioselective C-H bond activation, is complementary to a Friedel-Crafts type reaction giving the branched adduct.
