Chemical Properties
ALPHA-Bromostyrene is a clear yellow liquid or Pale yellowish mobile liquid. Almost insoluble in water, soluble in alcohol and oils. B.P. approximately 190℃. (decompose.). Pungent-sweet, gassy-floral odor, reminiscen~ of Hyacinth in extreme dilution. Slightly softer than the odor of omega-Bromostyrol.
Uses
alpha-Bromostyrene has been suggested as a modifier for the classic chemical omega-Bromostyrol, but does not seem to offer significant advantages. alpha-Bromostyrol is easily hydrolyzed in
the presence of water or mild acid to Aceto-phenone (which will affect the odor type significantly).
Uses
(1-Bromoethenyl)-benzene is a useful synthetic intermediate. It is a reactant used to synthesize Potassium (1-Phenylcyclopropyl)trifluoroborate (P698400). It can also be used in the synthesis of substituted cyclopentenones.
Preparation
From Styrene by treatment with Bromine. The resulting Styrene dibromide is treated with alcoholic KOH to yield alpha-Bromostyrol.
