Overview

This transition-metal-free method efficiently synthesizes N-heterocycles using blue light, highlighting its eco-friendly benefits.

Key Points

  • The dehydrogenative process achieves good to excellent yields across 59 examples of N-heterocycles.
  • A redox-active catalyst enables the transformation of benzylic alcohols into valuable aldehydes under blue light.
  • This method utilizes aerial-O2 as an oxidant, improving compatibility and selectivity compared to metal catalysts.
  • The proposed mechanism integrates various structural, electrochemical, and photophysical analyses, revealing new insights.
