An efficient synthesis for the following transformation is to be determined. Concept introduction : One carbon atom must be added to the final product in this process. Because the carbon-carbon triple bond in the final product has taken the place of the carbon-carbon double bond in the starting material, there is also a change in the identity of a functional group . Alkenes can be converted to terminal alkynes by first being brominated and then being eliminated. and the resulting alkyne can be methylated to produce the desired product.
