Phosphine Organocatalysis [PDF]
Chemical Reviews, 2018 The hallmark of nucleophilic phosphine catalysis is the initial nucleophilic addition of a phosphine to an electrophilic starting material, producing a reactive zwitterionic intermediate, generally under mild conditions. In this Review, we classify nucleophilic phosphine catalysis reactions in terms of their electrophilic components. In the majority of

Switchable organocatalysis from N-heterocyclic carbene-carbodiimide adducts with tunable release temperature [PDF]
, 2023 N-Heterocyclic carbenes (NHCs) are powerful organocatalysts, but practical applications often require in situ generation from stable precursors that “mask” the NHC reactivity via reversible binding.
