M. Curini et al., Potassium exchanged layered zirconium phosphate as base catalyst for the desilylation of phenol silyl ethers., SYN COMMUN, 30(17), 2000, pp. 3181-3187
Layered zirconium hydrogen phosphonate exchanged with the potassium ion was
found to be an efficient heterogeneous catalyst for the hydrolysis of ster
ically hindered phenolic silyl ethers.
