Several complex catalyst systems for the selective dimerization of aliphatic conjugated dienes have been reported. For example butadiene is dimerised with the catalyst which consisted of combinations of transition metal complexes and alkyl aluminium compounds 1) . Recently,

1 1,3-cis, trans-Cyclooetadiene ( 2) is an intriguing diene when considered in terms of the Diels-Alder reaction. A concerted 1,4-cycloaddition of an appropriate dienophile would give the unknown bicyclic system 2. This is to be contrasted with the possible 2 + 2 addition of the dienophile to ~ whi
## Abstract The thermal reaction of 1,3βbutadiene (BD) has been studied between 464 and 557Β°K at pressures between 49 and 450 torr. The products are 4βvinylcyclohexene (VCH) and __cis__, __cis__βcyclooctaβ1,5βdiene (COD), and their formations are second order. The rate constant (in 1/mol Β· sec) for
