Like combustion, the enthalpy of this reaction measures the relative stability of endocyclic versus exocyclic alkenes.
The Horiuti-Polanyi mechanism governs this reaction. A phosphorus-boron zwitterion with frustrated ion pairs carries out this reaction on imines. To enantioselectively synthesize menthol, Noyori used a ruthenium BINAP catalyst for an asymmetric variant of this reaction. Cyclooctadiene is attached to an iridium atom in a more common catalyst for it. Like combustion, the enthalpy of this reaction measures the relative stability of endocyclic versus exocyclic alkenes. This reaction takes place at high temperatures and pressures and proceeds by the adsorption of one reagent to metal. It uses poisoned palladium, Lindlar's catalyst, to reduce alkynes to cis alkenes. For 10 points, name this reduction in which unsaturated compounds become saturated through the addition of the lightest element.
