Oximes, hydrazones, semicarbazones and azines are converted to the corresponding carbonylcompounds using a combination of Zr(HSO4)4 and wet SiO2 in good to high yields under completely heterogeneous conditions.
Design, synthesis and evaluation of new α-nucleophiles for the hydrolysis of organophosphorus nerve agents: application to the reactivation of phosphorylated acetylcholinesterase
mechanism of their action was studied in details by kinetic analysis, HPLC and LC–MS methods. The most promising structures were then considered as potent in vitro reactivators of phosphylated acetylcholinesterase (AChE), which was confirmed by the preliminary results of AChE reactivation initially inhibited by VX.
