Equilibrium acidities of cinchona alkaloid organocatalysts bearing 6′-hydrogen bonding donors in DMSO
Literature Information
The pKa values of 18 cinchona alkaloid based organocatalysts bearing 6′-hydrogen bonding donors were determined by the overlapping indicator method in DMSO via UV spectrophotometric titrations. The pKa values are in the range of 6.76–20.24.
