Abstract
Rate constants for the deprotonation reaction of N-phenacyl-4-R-pyridinium bromides (R ¼ H, CH3, CN) with 1,4-diazabicyclo[2.2.2]octane
were measured in three silicon polypodands, Me2Si24, EtSi34 and PhSi34. Silicon polypodands as open molecular capsules lower the
deprotonation rates but increase the stability of the formed ylides in comparison to DMSO and water.
