The aliphatic carbon-carbon activation of c-octane was achieved via the addition of Rh(ttp)H to give Rh(ttp)(n-octyl) in good yield under mild reaction conditions. The aliphatic carbon-carbon activation was Rh(II)(ttp)-catalyzed and was very sensitive to porphyrin sterics.

Radical Smiles rearrangements have emerged as powerful methodologies for constructing carbon-carbon bonds through intramolecular radical addition and fragmentation under milder conditions, with SO released as a byproduct. However, SO-retaining Smiles rearrangements, which can yield valuable alkyl sulfone derivatives, have been scarcely explored. In this study, we present an unprecedented iron-catalyzed SO-retaining Smiles rearrangement initiated by the decarboxylation of aliphatic carboxylic acids.

The direct coupling of alkene feedstocks with aldehydes represents an expedient approach to the generation of new and structurally diverse C(sp)-hybridized alcohols that are primed for elaboration into privileged architectures. Despite their abundance, current disconnection strategies enabling the direct coupling of carbon-carbon π-bonds and aldehydes remain challenging because contemporary methods are often limited by substrate or functional group tolerance and compatibility in complex molecular environments. Here, we report a coupling between simple alkenes, heteroarenes and unactivated aliphatic aldehydes via an electrochemically induced reductive activation of C-C π-bonds.
