In our original article,1 reference [18] was not correct. We referred to references [2,3] and [3c], which are in fact references [4,5] and [5b,5c], respectively. Thus, reference [18] should read: [18] In agreement with previous observations in the case of fluorine-substituted enol ethers,4,5 the 19F NMR chemical shift is found to be on average 14.4 ppm more negative in the E isomer than in the Z isomer; The 2JCF coupling constants were found to be consistently lower in the Z isomer than in the E isomer, whereas the 3JCF coupling constant was found to be ca. 2.5 Hz in the Z isomer and near zero in the E isomer.5b,5c These correlations will be addressed in more detail in an upcoming paper.
