Irradiation of 1,4-dimethoxynaphthalene (DMNH) in the presence of 4-substituted benzyl chlorides (X-C6H4CH2Cl, X=H, Cl, CN or NO2) in the either acetonitrile or benzene solution results in benzylation of DNNH, predominantly at position 2 and to a lesser extent on the unsubstituted ring.Steady-state and flash photolysis studies show that charge transfer between singlet excited DMNH and the chlorides is involved.The reaction occurs predominantly in-cage via concerted electron transfer and carbon-chlorine bond cleavage with X=H or Cl, while with X=NO2 fragmentation of the benzyl chloride radical anion occurs out-of-cage, but the process in this case is much less efficient due to competing back electron transfer.
