✦ Synopsis

Recently studies on the application of simplified q&-equilibrium theory to the ment of phenyl acetates have suggested an effect correlated with electronegativity on of the rate for loss of ketene. That is, the "frequency factor" A in the expression rearrangeretardation is decreased substantially when fluorine is moved from the pcmz to the ortho position, but not so much when chlorine, bromine, or iodine is moved from the paru to the ortho position.
