, p. 147 - 156 (2013/01/15)
Intermolecular Pauson-Khand reaction of fluoroalkylated alkynes with 2-norbornene or 2,5-norbornadiene at the reflux temperature of dichloroethane proceeded smoothly to give the corresponding cyclopentenone derivatives in high yields as a mixture of regio

A novel method for the generation of 3,3,3-trifluoropropynyllithium is reported, which involves treatment of trifluoromethyl-substituted enol tosylate, prepared from 1,1-dichloro-3,3,3-trifluoroacetone, with two equivalents of butyllithium. Palladium-cata

(Chemical Equation Presented) Smooth and selective Payne rearrangement was achieved for the above types of epoxyalcohols with a CF3 group so as to form thermodynamically more stable alkoxides, where the strongly electron-withdrawing nature of this moiety played a significantly important role and was proved to overcome increased steric instability of epoxides from syn-E to anti-Z isomers.
