Analytical chemistry

Smuts JP, Hao XQ, Han Z, Parpia C, Krische MJ, Armstrong DW.
PMID: 24372088
Anal Chem. 2014 Jan 21;86(2):1282-90. doi: 10.1021/ac403686a. Epub 2013 Dec 27.

New cyclofructan-6 (CF6)-based chiral stationary phases (CSPs) bind barium cations. As a result, the barium-complexed CSPs exhibit enantioselectivity toward 16 chiral phosphoric and sulfonic acids in the polar organic mode (e.g., methanol or ethanol mobile phase containing a barium...

Chem Commun (Camb). 2007 Jun 14;(22):2222-4. doi: 10.1039/b702997g. Epub 2007 Apr 05.

Thanks to strong hydrophilic interactions between reaction products and the catalyst surface, mesoporous silica supported sulfonic sites were found to be much more selective than homogeneous and common solid acid catalysts.
