Determination of the Effective Charge Numbers and Ionic Mobilities of Single Isomer and Randomly Highly Sulfated Cyclodextrins by Capillary Isotachophoresis and Zone Electrophoresis. [PDF]

open access: yesElectrophoresis
ABSTRACT Sulfated cyclodextrins (CDs) are multiply negatively charged molecules widely used as chiral selectors in capillary electrophoresis (CE). In some of their applications, the effective charge numbers of their molecules were observed to be lower than the numbers of the attached sulfated groups due to strong binding of counterions. However, degree

Synthesis and Characterization of Hypercoordinated Silicon Anions: Catching Intermediates of Lewis Base Catalysis

open access: yesAngewandte Chemie, Volume 134, Issue 27, July 4, 2022., 2022
The Lewis superacid bis(perchlorocatecholato)silane serves as a binding platform for weak anionic donors, providing the first characterized anionic bromido, iodido, formato, acetato, triflato, and sulfato silicates. This set allows to evaluate the structural and electronic perturbation of silicon species and substantiates their role in Lewis base ...
