Many specialized dienes have been developed to exploit this reactivity for the synthesis of natural products (e.g., Danishefsky's diene). Other addition reactions. Conjugated dienes add reagents such as bromine and hydrogen by See more In organic chemistry a diene (diolefin (/daɪˈoʊləfɪn/ dy-OH-lə-fin) or alkadiene) is a covalent compound that contains two double bonds, usually among carbon atoms. They thus contain two alkene units, with the standard … See more On an industrial scale, butadiene is prepared by thermal cracking of butanes. In a similarly non-selective process, dicyclopentadiene is obtained from coal tars See more Dienes can be divided into three classes, depending on the relative location of the double bonds: 1. Cumulated dienes have the double bonds sharing a common atom. The result is more specifically called an allene. 2.
