AbstractHere we report a mild protocol for benzylic C−H trifluoromethylthiolation using sodium decatungstate (NaDT) as the photocatalyst. Wherein, photoactivated DT abstracted the benzylic hydrogen atom via a radical process. This transformation works well with a slight excess of benzylic substrates or as limiting reagents for better purification. The reaction shows mild conditions and good functional group tolerance. Moreover, the protocol could be applied to gram‐scale synthesis.
Metal‐ and Additive‐Free Electrochemical Oxidation of Benzylic C−X Bonds to Carbonyl Groups
A scalable electrochemical strategy for oxidation of various benzylic C−X bonds to carbonyl groups was achieved. The protocol runs under mild reaction conditions and airatmosphere in a simple undivided electrolysis cell, H2O as oxygen source, and cheap graphite plates as both, anode and cathode.
