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.
1 The Diels-Alder reaction is a conjugate addition reaction of a conjugated diene to an alkene (the dienophile) to produce a cyclohexene. 2  The simplest example is the reaction of 1,3-butadiene with ethene to form cyclohexene:3  The analogous reaction of 1,3-butadiene with ethyne to form 1,4-cyclohexadiene is also known: Due to the high degree of regio-and stereoselectivity (due to the concerted mechanism), the Diels-Alder reaction is a very powerful reaction and is widely used in synthetic organic chemistry.
