The transient absorption spectra obtained by the laser flash photolysis of 1,8-bis(substituted methyl)naphthalenes have been measured.By comparison with the transient spectra for 1-(substituted methyl)naphthalenes, the transient species absorbing at 430 nm observed from (PhO-CH2)2Naph is attributed to the triplet state.In the case of (PhS-CH2)2Naph, absorption bands at 490 and 430 nm due to PhS are observed in addition to an absorption band in the region of 310-400 nm, which is due to the carbon-centred radical CH2Naph(CH2-SPh)>.For (PhSe-CH2)2Naph, a new broad absorption band appeared in the region of 400-520 nm, which covered weak absorption bands due to PhSe at 430 and 490 nm.The new absorption is attributed to the carbon-centred radical CH2Naph(CH2-SePh)> in which there is considerable interaction between the CH2- and PhSe moieties.The possibility of a bridged radical for CH2Naph(CH2-SePh) is suggested by MO calculations.
