Overview

This study demonstrates efficient C─O and C─C bond cleavage in lignin using water microdroplets, suggesting a novel green approach.

Key Points

  • The spontaneous cleavage of C─O and C─C bonds in lignin achieved yields exceeding 70%, producing valuable phenols.
  • Mechanistic studies revealed that oxidation by molecular oxygen is crucial for Cα─Cβ bond cleavage in lignin.
  • The unique alkaline environment at the air–water interface of negatively charged microdroplets facilitates this process.
  • Mass spectrometry confirmed the identification of intermediates, paving the way for greener lignin cleavage methods.
