Abstract

It is demonstrated that 1, 3-dienes, in which a vinyl and alkyl group are cis, undergo a reversible thermal isomerization involving the over-all 1, 5-transfer of a hydrogen with concomitant migration of both carbon-carbon double bonds. At 350-450, depending on the nature of the dienes on hand, an equilibrium mixture is approached in which the more thermodynamically stable isomer predominates. Dienes in which a vinyl group and alkyl ...
