Electron self-exchange activation parameters of diethyl sulfide and tetrahydrothiophene
Beilstein Journal of Organic Chemistry, 2013 Electron transfer between the title compounds and their radical cations, which were generated by photoinduced electron transfer from the sulfides to excited 2,4,6-triphenylpyrylium cations, was investigated by time-resolved measurements of chemically ...
