title: Bond activation with an apparently benign ethynyl dithiocarbamate Ar-C≡C-S-C(S)NR2.
abstract: The hedgehog molecule: A simple ethynyl dithiocarbamate [Ar-C≡C-S-C(S)NR(2)] is able to cleave a broad range of enthalpically strong σ bonds and to activate carbon dioxide and elemental sulfur. Depending on the substrate, the bond activation process involves either the existence of an equilibrium with the nonobservable mesoionic carbene isomer or the cooperation of the nucleophilic carbon-carbon triple bond and the electrophilic CS carbon atom.
