International Journal of Electrochemical Science, 2007 Electrochemical oxidation of catechols (1a-e) has been studied in the presence of sulfite ion (3) as nucleophile in aqueous solution, using cyclic voltammetry and controlled-potential coulometry. The results indicate the participation of catechols (1a-e)

Superelastic and pH-Responsive Degradable Dendrimer Cryogels Prepared by Cryo-aza-Michael Addition Reaction [PDF]
, 2018 Dendrimers exhibit super atomistic features by virtue of their well-defined discrete quantized nanoscale structures. Here, we show that hyperbranched amine-terminated polyamidoamine (PAMAM) dendrimer G4.0 reacts with linear polyethylene glycol (PEG ...

Enantioselective Michael Addition of Water [PDF]
Chemistry – A European Journal, 2014 AbstractThe enantioselective Michael addition using water as both nucleophile and solvent has to date proved beyond the ability of synthetic chemists. Herein, the direct, enantioselective Michael addition of water in water to prepare important β‐hydroxy carbonyl compounds using whole cells of Rhodococcus strains is described.
