Abstract

In this study, we have synthesized activated tungstic acid by dehydration of tungstic acid as a highly efficient catalyst and employed it for the catalytic transformations of various alkenes. The importance of this series of studies is to help students to graphically visualize a diverse array of organic synthesis reactions. The alkenes react differently depending on their structure via mainly acid-catalyzed reactions that produce a whole range of products including coupled products (dimers). For example, Cyclopentene was transformed into 1,1'-bi (cyclopent-3-ene) in yield 100% at room temperature. Cyclohexene-3-cyclohexyl was form from Cyclohexene. The synthesized product was identified and confirmed by gas chromatography and mass spectroscopy, measuring the retention times of authentic samples of the compounds.
