... 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 ...

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.
