Diels alder reaction with a triple bond
WebMar 15, 2011 · Abstract. The Diels-Alder reaction consists in an addition of a compound containing a double or triple bond (usually activated by additional unsaturation in the alpha, beta-position) to the 1,4 ... WebExperiment 4: Diels-Alder Reaction Jeremy Wolf 7/21/2008 TA: Stefanie Lenz. Introduction: The purpose of this experiment was to demonstrate the formation of six- membered rings by cycloaddition, also known as a Diels-Alder reaction. In a cycloaddition reaction, a 1,3-diene reacts with an alkene, or dienophile, to produce a six-membered ring.
