A series of 2-acyl-1,3-cyclohexanediones were prepared and isomerization mechanisms of the corresponding enol esters were investigated. The driving force for this migration is likely that the intrinsic electrostatic repulsion between the 2-acyl oxygen atom and the two 1,3-diketone oxygens caused def
