Web18.19 The product of a Heck reaction is, like the starting material, an alkene. Why doesn’t a Heck reaction of the product compete with the reaction of the starting alkene? 18.20 What product is expected when cyclopentene reacts with iodobenzene in the presence of tri-ethylamine and a Pd(0) catalyst? B. The Suzuki Coupling WebSolution: Cyclopentene reacts with hydronium ions to form a carbocation that reacts with water to produce an alcohol, as shown below. The product is cyclopentanol. Addition reactions to alkynes are similar to additions to alkenes. For instance, hydrogen halides can be added to an alkyne by way of a mechanism similar to that of alkenes.
