Carbonyl-Photoredox/Metal Dual Catalysis: Applications in Organic Synthesis

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(sp 3 )–C(sp 3 ), C(sp 3 )–C(sp 2 ), C(sp 2 )–C(sp 2 ), C(sp 2 )–O, and C(sp 3 )–O bond formatio...

Description
Summary: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(sp 3 )–C(sp 3 ), C(sp 3 )–C(sp 2 ), C(sp 2 )–C(sp 2 ), C(sp 2 )–O, and C(sp 3 )–O bond formation induced by readily available and inexpensive carbonyl complexes as single electron transfer agents, photosensitizers, or hydrogen atom transfer agents. 1 Introduction 2 Homocoupling of Aryl Halides 3 Functionalization of C(sp 3 )–H Bonds 3.1 Dehydrogenation of Alkanes 3.2 Arylation/Alkylation 3.3 Carboxylation 3.4 Acylation 3.5 Hydroalkylation of Olefins 3.6 Hydroalkylation of Imines 4 Benzoylation of Aryl Bromides 5 Aryl Esterification 6 Oxidation of β-Keto Esters 7 Conclusions and Future Outlook
