Homework Help: Organic: Alkyne to Alkene

  1. Oct 13, 2011 #1
    Organic: Alkene to Alkyne

    I am trying to do a synthesis of 2-Octyne from 1-heptene. Conversion of the triple bond to a double bond is pretty easy, but i also have to add an alkyl group, and the double bond must remain on the original triple bond location.

    Thus, so far thoughts:
    1. remove hydrogens from double bond

    2. add ch3 to terminal carbon to replace hydrogen.
    CH3-BR ?

    Question 2: Propose a synthesis of cis-3-octene starting from 1-hexene.
