Reaction of 1,5-diphenyl-3-arylverdazyles with СН-acids

详细

The presence of electron-donor substituents in the phenyl ring at the atom С³ of the tetrazinyl ring increases, and of electron-acceptor substituents reduces the reaction rate of 1,5-diphenyl-3-arylverdazyl radicals with СН-acids. The reaction is described with a kinetic equation of the second order with respect to verdazyl, the process rate is determined by the energy of the electron transfer from the SOMO (singly occupied molecular orbital) of the radical to the LUMO of the СН-acid.
