Аннотация:
The HCl-catalyzed hydrolysis of dialkyl arylphosphonates monitored by 31P NMR spectroscopy has revealed two consecutive steps characterized by pseudo first order rate constants k1 and k2. A reactivity order for the two steps and for the overall two step hydrolysis has been derived depending on the alkoxy and aryl substituents. Besides the AAc2 mechanism, the AAl1 route has been substantiated for the PriO substituent.
