Matrix photoionization of alkyl- and dialkylbenzenes produced and trapped the parent radical cations.Irradiation in the visible parent cation absorption induced α-H transfer to the cation ring to give substituted methylenecyclohexadiene cations.The ease of 1,3-hydrogen transfer in these experiments suggests that this may be an important rearrangement in gaseous alkylbenzene cations.Subsequent ultraviolet photolysis of these samples produced substituted styrene cations.

Matrix photoionization experiments with chloro- and bromostyrenes at high dilution in argon have produced and trapped the parent cations as identified by strong absorptions in the red and near-UV regions.Photolysis rearranged the α isomers to the Z and E β isomers with a larger yield of the E β isomer.The Z- and E-β isomers were interconverted by selective photoexcitation.Photolysis of α-bromostyrene cation also produced the phenylacetylene cation.
