Paper Abstract

We have measured time-dependent absorption spectra following nanosecond laser photolysis of some nitrotoluenes in several solvents. In non polar media, rapid intra-molecular hydrogen atom transfer occurs in electronically excited 2,4-dinitrotoluene to yield the aci-quinoid isomer, which is observed as a broad transient absorption. In methanol and in acetonitrile the initial aci-form subsequently undergoes deprotonation with a first-order rate constant of ca. 2 x 105 s-1, to form the 2,4-dinitrobenzyl anion. The corresponding anion is also generated from 2,4,6-trinitrotoluene in methanol, but we have been unable to demonstrate that its production occurs via the aci-form.
