Abstract
Photoredox/metal dual catalysis is a versatile tandem methodology to construct carbon–carbon
and carbon–heteroatom bonds. The focus of this short review is the application of
this technology to C(sp3)–C(sp3), C(sp3)–C(sp2), C(sp2)–C(sp2), C(sp2)–O, and C(sp3)–O bond formation induced by readily available and inexpensive carbonyl complexes
as single electron transfer agents, photosensitizers, or hydrogen atom transfer agents.
