Kunitake, Toyoki published the artcileCatalytic hydrolysis of dinitrophenyl sulfate by polyethylenimine derivatives, Category: esters-buliding-blocks, the publication is Bulletin of the Chemical Society of Japan (1979), 52(8), 2402-8, database is CAplus.
The catalytic hydrolysis of nitrophenyl sulfates by poly(ethylenimine) (PEI) derivatives was investigated at 30° in aqueous buffers. The catalytic hydrolysis of 2-hydroxy-5-nitrophenyl sulfate by an PEI with imidazolylmethyl and dodecyl substituents failed to proceed in spite of the contrary report by Kiefer et al. 2,4-Dinitrophenyl sulfate was cleaved fairly readily by PEI derivatives Simple sulfate transfer was observed in the case of alkylated PEI, but the catalytic hydrolysis proceeded according to the Michaelis-Menten kinetics in the case of quaternized PEI. Partly quaternized PEI’s showed highest catalytic efficiencies reported to date for the hydrolysis of dinitrophenyl sulfate. Nitrophenyl sulfates were not cleaved by these polymers.
