11. Catalyzed hydroboration-oxidation of substituted alkenes can be rendered enantioselective. 12. Many higher alcohols are produced by hydroformylation of alkenes followed by hydrogenation. 13. More useful is the E1 elimination reaction of alcohols to produce alkenes . 14. Lithium aluminium hydride does not reduce simple alkenes or arenes. 15. One way to observe this distortion is in pyramidal alkenes . 16. The compound is widely used as a catalyst for hydrogenation of alkenes . 17. In alkene radicals proton abstraction to an alkyne is preferred. 18. Difluoroalkenes are alkenes that have two fluorines on their sp 2 carbon. 19. Generally, the alkenes are known to react with electrophiles. 20. Alkenes can also be oxidised and cleaved in the Lemieux Johnson oxidation.
