The title compounds were prepared and examined as catalysts for the hydrolysis of p-nitrophenyl tetrahydropyranyl ether at low pH and the exchange of p-tert-butylphenacyl alcohol tritiated in the methylene group at high pH. All three isomers, as the phosphate dianions, were effective catalysts for the latter reaction, in which the functional group assists enolization of the bound ketone. Only the 3-phosphoric acid isomer showed net catalysis of the former reaction, bound substrate being hydrolyzed with the assistance of a monoanion phosphoric acid group.
