چکیده
The title compound, C(9)H(9)BrO(2), prepared by the reaction of 4-methoxy-acetophenone and cupric bromide, , is approximately planar (r.m.s. deviation 0.0008 Å). In the crystal, weak inter-molecular aromatic C-H⋯O(carbon-yl) hydrogen-bonding inter-actions result in a one-dimensional chain structure.

An electron-transfer chain reaction between 2-nitropropane anion and αbromoketones derived from nitrobenzene and nitrothiophene was demonstrated by mechanistic study and a specific convenient synthetic protocol. Thus, 2-bromo-1-(5nitrothiophen-2-yl)ethanone or 2-bromo-1-(4-nitrophenyl)ethanone were reacted with several cyclic nitronate anions to form α,β-unsaturated ketones via a SRN1 mechanism...
