Construction of Carbon-Carbon(Ar-C) Bond via
Photogenerated Intermediates
2. INTRODUCTION
1. Carbon-Carbon bond formation via various photochemical and
photocatalytic methods.
2. Photochemical generated intermediates; aryl radicals, benzyl radicals,
simple radicals and carbenes
3. Photoredox catalysts like Eosin Y, Ru(bpy)2+, Cu(dpp)2
+ by activating in
the presence of visible light.
4. Ar-C bond formation by ipso substitution of various functional groups.
17. Summary
Starting with the importance and application of photochemical reactions we
introduced the generation of reactive intermediates like radicals, biradicals,
radical ions, cations & anions and carbenes in the presence of photoredox
catalysts like eosin Y, rose Bengal and other Ir & Ru based catalysts,
irradiating via visible light of different intensities and also sometimes UV
light. We proceeded with Ar-C bond formation via ipso substitution of
various functional groups.
From discussion we anticipate these photoredox or photochemical reactions
will find broad applications among practitioners of organic synthesis.
