... Synthesis of Alkene - Elimination Though alkenes can be made by the cracking of alkanes (can be called dehydrogenation), this would only be used on a specific alkane (e.g. propane) to produce a specific alkene (e.g.propene) when part of a Synthesis. The other option would be to perform an Eliminatio ...

Octenes from E1 versus E2 Eliminations
... In an E2 reaction, the base abstraction of a proton and the expulsion of the leaving group occurs simultaneously to form the C=C. The dehydrobromination of 1-bromooctane with the strong base, potassium tert-butoxide, in triethylene glycol demonstrates the E2 elimination reaction: H CH3 ...

Elias James Corey
Elias James ""E.J."" Corey (born July 12, 1928) is an American organic chemist. In 1990, he won the Nobel Prize in Chemistry ""for his development of the theory and methodology of organic synthesis"", specifically retrosynthetic analysis. Regarded by many as one of the greatest living chemists, he has developed numerous synthetic reagents, methodologies and total syntheses and has advanced the science of organic synthesis considerably.
