The product of the reaction shown is to be determined. Concept introduction: 1,3-dipoles are represented by a Lewis structure such that four electrons are delocalized over three atoms. One of them is positively charged while the other is negatively charged. This dipole acts as a 4π electron component and can add to a 2π electron component via the [4+2]-cycloaddition . The 2π electron component can also be an alkyne which changes to an alkene upon addition. The resultant structure contains a new five membered ring consisting of the 1,3-dipole attached to the two atoms of the alkyne. The triple bond between the carbon atoms of the alkyne changes to a double bond.
