Hydrogen bond and potassium cation mediated preorientation were detected fo
r phthalimido acetic acid and the corresponding acetate. Evidence for these
phenomena came from X-ray structure analysis as well as cyclic voltammetri
c and IR spectroscopic measurements. These interactions rationalize the pho
toinduced electron transfer (PET) reactivity of the substrates in photodeca
rboxylation reactions.
