Hydrohalogenation Reaction of 1,2-Allenyl Ketones Revisited. Efficient and Highly Stereoselective Synthesis of β,γ-Unsaturated β-Haloketones.

-It is shown that in the presence of AcOH 1,2-allenyl ketones can be selectively transformed into β,γ-unsaturated β-haloketones. Under these mild acidic conditions, isomerization to α,β-unsaturated ketones is suppressed.
