The Baker-Venkataraman rearrangement is the chemical reaction of 2-acetoxyacetophenones with base to form 1,3-diketones.[1][2]
This rearrangement reaction proceeds via enolate formation followed by acyl transfer.
The Baker-Venkataraman rearrangement is often used to synthesize chromones and flavones.[3]
