In a reaction of this type, di-cobalt-octa-carbonyl acts as a source of carbon monoxide to a reacting alkyne and alkene. An isoxazolidine results from a reaction of this kind between a nitrone and an alkene. In the first step of ozonolysis, a molozonide forms due to this type of reaction between ozone and an alkene. A widely-used reaction of this type, between an alkyne and an azide, is the premier example of click chemistry. In their best-known example, the (*) endo transition state is favored. They are notated by placing, in square brackets, the number of electrons contributed by each reactant, separated by plus signs. In the most famous reaction of this type, a diene and dienophile react together. For 10 points, the Diels-Alder reaction is a reaction of what type, in which the reactants join together to form a ring?
In a reaction of this type, di-cobalt-octa-carbonyl acts as a source of carbon monoxide to a reacting alkyne and alkene.
