Abstract:
Herein, we show that redox tag-guided intermolecular formal [2 + 2] cycloaddition can be used as a probe to investigate intramolecular single-electron transfer (SET) mechanisms. The efficacy of intramolecular SET can be evaluated in association with concomitant carbon-carbon bond formation and/or cleavage, leading to cycloaddition or cross-metathesis. Experimental and theoretical results suggest that the intramolecular SET is under both thermodynamic and kinetic control and can also occur through bonds, not only through space.

Some chemical reactions can be classified as reduction-oxidation reactions, or redox reactions. Oxidation is the process of matter, like an atom or ionic molecule, losing one or more electrons, and reduction is the process of the matter gaining one or more electrons.
Oxidation States
Each atom in a molecule has its own oxidation state or oxidation number. The oxidation state describes how oxidized a molecule is relative to its free elemental form. The oxidation state is...
