-diphenyl substituted allylic cations are generated within ZSM-5 and mordenite as persistent species by adsorption of 1-acetoxy-1,3-diphenylpropane and 1,5-diacetoxy-1,5-diphenylpentane onto the H+-form of these zeolites; the diffuse reflectance spectra of these highly coloured samples (orange or pink) matches the very characteristic absorption spectra of these allyl cations in homogeneous solution; the non-acidic Na+-form of these zeolites does not have the same effect.
