In the present communication we will report the results from our study on the generation and reactivity of sulfide radical cations in solution. PET by different sensitizers will be employed for ionization of the substrate; and the effect of electron withdrawing and electron donation groups (R) on the fragmentation rate constant will be evaluated. Tools such as preparative photolysis, transient absorption spectroscopy and electrochemical methods will be used in order to gain insights into the reaction mechanism, and to evaluate the different channels these radical cations would follow.
