A Practical, Two-Step Synthesis of 2-Substituted 1,3-Butadienes
摘要:
A two-step procedure for preparing 2-alkyl-1,3-butadienes is described. Cuprate addition to commercially available 1,4-dibromo-2-butene yields 3-alkyl-4-bromo-1-butene, a product Of S(N)2' substitution. Dehydrohalogenation gives 2-alkyl-1,3-butadienes.
