K. Iseki et al., DIASTEREOSELECTIVE PERFLUOROALKYLATION OF CHIRAL IMIDE ENOLATES WITH PERFLUOROALKYL IODIDES MEDIATED BY TRIETHYLBORANE, Journal of fluorine chemistry, 74(2), 1995, pp. 269-271
The perfluoroalkylation of lithium enolates of chiral N-acyloxazolidin
ones with perfluoroalkyl iodides mediated by triethylborane proceeds w
