Absorption Spectra and Photochemical Rearrangements of Alkyl- and Dialkylbenzene Cations in Solid Argon

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.
