Redox processes are at the heart of synthetic methods that rely on either electrochemistry or
photoredox catalysis, but how do electrochemistry and photoredox catalysis compare? Both …

Photoredox chemistry with organic or transition metal agents has been reviewed in earlier
years, but such is the pace of progress that we will overlap very little with earlier …

Alkyl radicals are key intermediates in organic synthesis. Their classic generation from alkyl
halides has a severe drawback due to the employment of toxic tin hydrides to the point that …

As the “chemical chameleon”, sulfonyl-containing compounds and their variants have been
merged with various types of reactions for the efficient construction of diverse molecular …

The exceptional versatility of sulfones has been extensively exploited in organic synthesis
across several decades. Since the first demonstration in 2005 that sulfones can participate …

Photoredox catalysis has experienced a revitalized interest from the synthesis community
during the past decade. For example, photoredox/Ni dual catalysis protocols have been …

A dual photochemical/nickel-mediated decarboxylative strategy for the assembly of C (sp3)–
C (sp2) linkages is disclosed. Under light irradiation at 390 nm, commercially available and …

Recent advances in the sulfonylation of alkenes via the insertion of sulfur dioxide are
summarized. The sulfur dioxide surrogate of DABCO·(SO2) 2 or inorganic sulfites is used in …

Abstract Radical/Polar Crossover (RPC) chemistry is a rapidly growing subset of photoredox
catalysis that is characterized by transformations featuring both radical and ionic modes of …

The combination of photoredox catalysis with the Wolff–Kishner (WK) reaction allows the
difunctionalization of carbonyl groups by a radical-carbanion relay sequence (photo-Wolff …
