Abstract

Abstract: The hydrolysis reactions of three aryl-substituted spirobicyclic oxyphosphoranes (Ia- c) have been studied in aqueous solution. These are characterized by an H+-catalyzed reaction extending to about pH 9.54 sharply changing there to an OH--catalyzed reaction. The acid reaction is general acid catalyzed (a= 0.74) and appears to be a dissociative process directly analogous to the general acid catalyzed hydrolysis of an acetal or ortho ...
