Summary In the previous work it has been shown that metallic sodium is a better reagent for the transformation of o-aroyloxyacetoarones to the corresponding o- hydroxydiaroylmethanes. It has now been observed that metallic sodium can be conveniently used even for the transformations of o-acyloxyacetoarones which finally give 3- acyl-2-alkylchromones or 2-alkylchromones Thus o-acetoxyacetophenone when treated ...
