Excited (triplet) states offer a myriad of attractive synthetic pathways, including
cycloadditions, selective homolytic bond cleavages and strain-release chemistry …

Benefiting from the impressive increase in fundamental knowledge, the last 20 years have
shown a continuous burst of new ideas and consequently a plethora of new catalytic …

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 …

Asymmetric catalysis is a major theme of research in contemporary synthetic organic
chemistry. The discovery of general strategies for highly enantioselective photochemical …

For molecules with a singlet ground state, the population of triplet states is mainly possible
(a) by direct excitation and subsequent intersystem crossing or (b) by energy transfer from …

Naturally evolved enzymes, despite their astonishingly large variety and functional diversity,
operate predominantly through thermochemical activation. Integrating prominent …

Energy transfer can leverage the enormous potential of excited-state reactivity. Through"
indirect excitation" of substrates, otherwise elusive reactivity modes can be switched on …

As the breadth of radical chemistry grows, new means to promote and regulate single-
electron redox activities play increasingly important roles in driving modern synthetic …

Stereochemical enrichment of a racemic mixture by deracemization must overcome
unfavorable entropic effects as well as the principle of microscopic reversibility; recently …

All chemists are familiar with the idea that, at equilibrium steady state, the relative
concentrations of species present in a system are predicted by the corresponding …
