21. Chiral cylcodiphosphazanes have found use as ligands in asymmetric catalysis . 22. I don't think nucleophilic or Lewis acid catalysis is involved. 23. Catalysis by anionic catalysts is also called asymmetric counteranion-directed catalysis.24. Catalysis by anionic catalysts is also called asymmetric counteranion-directed catalysis . 25. Chiral anion phase-transfer catalysis was introduced by Toste in 2007. 26. His area of specialization is Heterogeneous Catalysis / Reaction Engineering. 27. The distal face is used for substrate binding and catalysis . 28. Prp8 has also been hypothesized to be a cofactor in RNA catalysis . 29. He is the Swiss representative of the European Federation of Catalysis Societies. 30. The fluorodecarboxylation of carboxylic acids can also be triggered using photoredox catalysis .
