Microwave-Assisted Organic Synthesis in the Organic Teaching Lab: A Simple, Greener Wittig Reaction
Martin, Eric; Kellen-Yuen, Cynthia
Journal of Chemical Education, v84 n12 p2004-2006 Dec 2007
A greener, microwave-assisted Wittig reaction has been developed for the second-semester organic teaching laboratory. Utilizing this microwave technique, a variety of styrene derivatives have been successfully synthesized from aromatic aldehydes in good yields (41-68%). The reaction not only occurs under neat reaction conditions, but also employs an inexpensive, non-pyrophoric base and readily available glassware. The average reaction times have been reduced to a matter of minutes rather than the hours typical of literature procedures. This method will therefore provide a quick and easy example of a Wittig reaction that can be accomplished in any undergraduate organic lab. The mixture of cis and trans alkenes produced by this method also provides instructors with opportunities to emphasize spectroscopic analysis of product mixtures.
