Oxidative Photoredox-Catalytic Activation of Aliphatic Nucleophiles for C(sp3)-C(sp2) Cross-Coupling Reactions

In the light you will find the road (Led Zeppelin): Visible-light photoredox catalysis leads the way in overcoming the reactivity limitations of alkyl nucleophiles in cross-coupling reactions. Iridium-triggered oxidative ph...

Platinum(II)-mediated dehydrosulfurization and oxidative carbon-carbon coupling in the gas-phase decomposition of thioethers

The ion/molecule reaction of [Pt(bipy ? H)]+ (bipy = 2,2'-bipyridine) with dimethyl sulfide leads to the loss of ethene in the main reaction channel. This process corresponds to a formal dehydrosulfurization (DHS) accompanied by
