Interplay of Chloride Levels and Palladium(II)-Catalyzed O-deallenylation Bioorthogonal Uncaging Reactions The palladium-mediated uncaging reaction of allene substrates remains a promising yet often overlooked strategy in the realm of bioorthogonal chemistry. This method exhibits high kinetic rates, rivaling those of the widely employed allylic and propargylic protecting groups.

A series of Ni(0) nanocatalysts was prepared from Ni(COD)2 complex in the presence of different stabilizers (hexadecylamine, polyvinylpyrrolidone PVP, PVP/triphenylphosphine, octanoic acid and stearic acid) for their evaluation in the selective hydrogenation reaction of ?,?-unsaturated carbonyl compounds by H2 under mild reaction conditions, i.e., low H2 pressure, temperature and catalyst loading.
