3. For the reaction sequence shown below, give the product of each reaction and show the mechanism of Its formation. 4. Propose a synthesis (make) for the compounds shown below. All carbon containing compounds, reagents, or reactants must be synthesized from the starting materials shown in the box. You may use any Inorganic compounds you wish. You may also use any solvents you wish, however, if a solvent participates in the reaction you must synthesize it.

ethers and epoxides can both undergo acid-catalyzed or base-catalyzed substitution reactions. Pimobendan (shown below) is a cardiac drug used to treat dogs with congestive heart failure. Pimobendan is taken orally, so it has the potential to react with stomach acid (HCl). Using your knowledge of ether reactions, predict if the ether functional group in Pimobendan is likely to react in a dog's stomach. If you think no reaction will occur, explain. If you think a reaction will occur, describe...

The purpose of this experiment is to synthesize a polymer using a Gilch polymerization of 2,5- bis(bromomethyl) - 1 -methoxy-4-(2-ethylhexyloxy) benzene, to investigate the polymer's photophysical properties, and to understand the mechanism of the polymerization reaction. Introduction Poly(p-phenylene vinylenes), or PPVS, are highly luminescent polymers that are used for a variety of commercial applications. Their general structure is shown in Figure . PPVS can be synthesized via a number of routes, including a Gilch polymerization reaction, which will be used...

Consider this reaction: tempe CHOWE HY CH2OH - + Br—Br H3C01 The mechanism proceeds through a first cationic intermediate, intermediate 1. Nucleophilic attack leads to intermediate 2, which goes on to form the final product. In cases that involve a negatively charged nucleophile, the attack of the nucleophile leads directly to the product.
