    Concepts and Reason
    Reduce Alkynes to trans-Alkenes An alkyne can be described as an unsaturated hydrocarbon that has a triple carbon-carbon bond ( ). In the presence of sodium or lithium, the carbon-carbon triple bonds can react to form a trans-alkene with a carbon-carbon( C = C).
    Anti-addition:
    Anti-addition can be defined as adding two substitutes to the opposite ends of a triple-bonded to create the anti-addition product.
    Fundamentals
    Reaction of alkyne and Li metal A trans-alkene of an alkyne is formed by combining it with lithium metal in an aromatic ethylamine solvent. The solvent can also act as a reducing agent and then the ammonium chloride salt is added. This is an example: R-C5 -R 1. Li, CH3CH2NH2 – 2. NH4Cl Alkyne R Trans Alkene Mechanism: nm - Ice cream R -c ác-R Li – c=ce L: CH3NH Alkyne Ć + CH3NH® Li® = + CH3NH® Li® H R. trans-alkene C2H5NH

    Fundamentals

    Reaction of alkyne and Li metal

    A trans-alkene of an alkyne is formed by combining it with lithium metal in an aromatic ethylamine solvent. The solvent can also act as a reducing agent and then the ammonium chloride salt is added. This is an example:


    R-C5 -R 1. Li, CH3CH2NH2 – 2. NH4Cl Alkyne R Trans Alkene

    Mechanism:


    nm - Ice cream R -c ác-R Li – c=ce L: CH3NH Alkyne Ć + CH3NH® Li® = + CH3NH® Li® H R. trans-alkene C2H5NH


    Formation intermediate of radical anion:


    C= C- c=ce L® Alkyne


    Formation and use of vinyl radicals:


    c=ce L® CHÚNH + C2H5NHPL:


    Formation and use of vinylic anion



    Formation of the trans-alkene


    - Bing + C2H3NH® Li® C2H5NH trans-alkene anti addition product

    Ans:


    | 1. 2 Li, C,H,NH, -78 °C - 2. NHCl 0- Trans product
