The reaction of CFPA chloride (2b) with pinacolyl alcohol was found to proceed more than 500 times faster than that of MTPA chloride (1b) suggesting that the CFPA method induces potentially much less kinetic resolution than the widely used MTPA method in
The Remarkably High Reactivity of α-Cyano-α-fluorophenylacetyl Chloride (CFPA-Cl) towards Hindered Nucleophiles in Enantiomeric Excess Determination
Takeuchi, Yoshio,Itoh, Noriaki,Koizumi, Toru

The reaction of PhCF(CN)COCl 2b with 3,3-dimethylbutal-2-ol 5 was found to proceed more than 500 times faster than that of PhCCF3(OMe)COCl (MTPA-Cl) 1b, suggesting that the CFPA method should potentially lead to much less kinetic resolution than the curre
