There is disclosed a process for the isomerization of a branched diene which comprises passing the branched diene in the vapor phase over a boron phosphate catalyst, the improvement comprising a catalyst which has an initial molar ratio of P/B of less than 1.0 but more than 0.6.
Diels-Alder Reaction. The [4+2]-cycloaddition of a conjugated diene and a dienophile (an alkene or alkyne), an electrocyclic reaction that involves the 4 Ï-electrons of the diene and 2 Ï-electrons of the dienophile.The driving force of the reaction is the formation of new Ï-bonds, which are energetically more stable than the Ï-bonds.verlap of the molecular orbitals (MOs) is required: Overlap between the highest occupied MO of the diene (HOMO) and the lowest unoccupied MO of the dienophile (LUMO) is thermally allowed in the Diels Alder Reaction, provided the orbitals are of similar energy.
