This document appears to be summarizing the results of an experiment testing different reaction conditions and substrates. It includes tables reporting yields, diastereoselectivity, and E:Z ratios for 10 different entries using various R1 and R2 groups. The tables also include results reported in brackets for comparison. Sections of text discuss the use of n-BuLi and t-BuOK in the reactions and 19F NMR characterization of products. Diagrams show structures of reactants and products involved in the transformations studied.
