... Ballantine et al., 1981a, 1981b). In many studies carbonium ions, formed by the protonation of the reactant molecules, have been considered to be essential intermediates in the reactions. The protons originate from the dissociation of interlayer water molecules coordinated to the exchangeable cation ...

Clean kinetic resolutions of extraordinarily high enantioselectivities were attainable with a wide range of UNCAs bearing various substituents and protecting groups (Table 3). Using the same extractive procedure for the isolation of 3a and ...
