WebThe major side reaction is elimination from the alkyl halide. You are using a strong base, an alkoxide ion. So you cannot use a tertiary alkyl halide at all -- it will undergo preferential elimination of HX. Primary alkyl halides are best, because they give primarily substitution reactions (ether formation). Web19.8: Using LDA to Form an Enolate Ion. Last updated.

WebDec 30, 2024 · Planning a Williamson Ether Synthesis. The Williamson ether synthesis has the same limitations as other S N 2 reactions, as discussed in Section 11-3.Since alkoxide anions are strong bases, utilizing 2 o or 3 o halogen leaving groups could possibly produce an E2 elimination product. When considering the synthesis of an unsymmetrical ether, … Web10% DVE-3 had the highest consumption of vinyl ether and no residual monomer could be detected. Thus, all divinyl ether must have been polymerized with at least one vinyl ether group. The polymerization rate (figure 6) of the pure radical reaction shows that the epoxy acrylates react faster than DVE-3 and the network formation is on
