They can also be created fromcarbonyls using an ylide in the Wittig reaction, but the easiest way to produce them is through a bimolecular E2 reaction.
The Tebbe reaction uses a metal carbenoid to create molecules of this functional class, while the Peterson reaction allows chemists synthesizing them to favor a specific stereoisomer. Only one stereoisomer can be generated by the Julia reaction because its last step requires that R-chains be anti- to one another. They can also be created fromcarbonyls using an ylide in the Wittig reaction, but the easiest way to produce them is through a bimolecular E2 reaction. FTP, identify these molecules, such as ethene or propene, characterized by a carbon-carbon double bond.
