473 K in order to examine the relation between the product distribution and the reaction mechanisms. Over ZrO2 the most abundant product was 4-ethyltoluene, which was produced by a base-catalyzed Diels–Alder reaction between BD and IPN, followed by double-bond migration and dehydrogenation. In the Diels–Alder reaction, IPN acts as a diene and BD acts as a dienophile. Over MgO, o-xylene was primarily

7-Methyl-trans-bicyclo[4.1.0]hept-3-ene has been synthesized and the thermal and transition-metal-complex promoted rearrangements of trans-bicyclo[4.1.0]hept-3-ene, 7-methyl-trans-bicyclo[4.1.0]hept-3-ene, and 7,7-dimethyl-trans-bicyclo[4.1.0]hept-3-ene have been compared.

Naturallyoccurring bulky terpenes, such as (+)‐ and (–)‐limonene and (–)‐β‐pinene, were quantitatively copolymerized with maleimide (MI) derivatives (i.e., phenyl‐, cyclohexyl‐, ethyl‐, and unsubstituted‐MI) in PhC(CF3)2OH solvent via selective 1:2‐alternating propagation governed by the penultimate effect, which resulted in 1:2‐sequence regulated polymers with relatively high glass transition temperatures
