One-Electron Transfer in the Reaction of Red Phosphorus with 4-Phenylthiobenzophenones in Superbasic Systems MOH/DMSO

Key Points

• This research aims to investigate the one-electron transfer mechanism in the reaction of red phosphorus with phenylthiobenzophenones in superbase systems.
• Conducted reactions at 85°C for 1.5–4 hours under argon atmosphere.
• Utilized EPR to detect the formation of an anion radical.
• Isolated reaction products and identified them using NMR analysis.
• Confirmed the formation of an anion radical from the reaction mixture.
• Isolated functional diarylmethanols and diarylmethanes with phenylthio groups.
• Identified products including bis[phenyl(4-(phenylthio)phenyl)methyl]- and bis[di(4-(phenylthio)phenyl)methyl]potassium phosphates.
