Synthesis from carbonyl compounds Another important method for alkene synthesis involves construction of a new carbon–carbon double bond by coupling of a carbonyl compound (such as an aldehyde or ketone ) to a carbanion equivalent. (35 words)
The oxidation can be stopped at the vicinal diol rather than full cleavage of the alkene by using milder (dilute,lower temperature) KMnO 4 or with osmium tetroxide or other oxidants. (31 words)
Example sentences (17)

This contains the alkene functional group and can now dimerize with another isobutene to give iso-octene, which is then catalytically hydrogenated to iso-octane using pressured hydrogen gas.
Thus they add two equivalents of bromine whereas an alkene adds only one equivalent in the reaction.
