Draw the neutral organic product for the following reaction. Show stereochemistry clearly.
Reduction of Alkynes to trans-Alkenes:
An alkyne is an unsaturated hydrocarbon which has a carbon-carbon () triple bond. The carbon-carbon triple bond can react with sodium or lithium in the presence of liquid ammonia or amine solvent to give a trans-alkene containing a carbon-carbon () double bond.
Anti-addition:
Anti-addition is defined as the addition of two substituents to opposite sides of a triple bond to form the anti-addition product.
Reaction of alkyne with Li metal:
An alkyne is reduced to a trans-alkene with lithium metal in an ethyl amine solvent which can act as a reducing agent, followed by the addition of ammonium chloride salt. For example,
Mechanism:
Formation of the radical anion intermediate:
Formation of the vinyl radical:
Formation of the vinylic anion:
Formation for the trans-alkene:
