Webalkenes. Primary alcohols undergo dehydration reactions to form alkenes via the concerted E2 mechanism43 due to the instability of primary carbocations,9 however, the pathways for the dehydration of secondary alcohols are not as clear.43 E1 and E2 mechanisms are both possible (Scheme 2) and yields can often be lower as well. WebDehydration of Alcohols to Yield Alkenes. One way to synthesize alkenes is by dehydration of alcohols, a process in which alcohols undergo E1 or E2 mechanisms to lose water and form a double bond.
