<p>2-Ethylpent-4-enoic acid is an analog of 4-pentenoic acid that can be used as a catalyst in the gas phase. It has been shown to catalyze the metathesis of cis and trans 4-pentene. 2-Ethylpent-4-enoic acid has an enthalpy of formation of -5.6 kJ/mol and an enthalpy of activation at 298 K of -2.8 kJ/mol, which means that it is a relatively strong catalyst for this reaction. 2-Ethylpent-4-enoic acid has also been shown to have a higher catalytic activity than 1,3,5,7,9,11,-heptadecane (1HPD) or 1,3,5,7,-octadecane (OD).</p>

<p>Cis-4-methyl-2-pentene is an unsaturated fatty acid that has been investigated as a model molecule for studying the effects of chlorine and chloride. Cis-4-methyl-2-pentene reacts with thianthrene to form monoadducts, which are compounds with only one reactive site. The reaction scheme involves two steps: (1) the chlorine atom in cis-4-methyl-2-pentene attacks the double bond on thianthrene to form a reactive intermediate and (2) this intermediate reacts with cis-4-methyl-2-pentene to form the monoadduct. The activation energies for these two steps have been determined using constant rate experiments. Aziridines are a series of organic compounds that can be formed from cis-4 methyl 2 pentene and are used as model molecules for studying reactions of organic compounds with chlorine.</p>
