Determining Elementary Stages of the Photoreduction of Thiocarbonyl Compounds from the Effects of the Chemical Polarization of Nuclei

Effects of the chemical polarization of nuclei are used to establish mechanisms and elementary acts of the photoreduction of diphenylmethanethione, bis(4-methylphenyl)methanethione, 2.6-dimethylcyclohexa-2.5-diene-1.4-dithione with triethylamine and 1,4-diazabicyclo-2,2,2-octane and 2-mercaptoethanol. Photoreduction proceeds in two stages (the transfer of an electron, and then a proton) or one (the transfer of a hydrogen atom). A mechanism for identifying intermediate particles is proposed.
