What are the conditions necessary for alkene reactions?
- Alkenes are primarily prepared by elimination reactions of molecules that contain good leaving groups attached to sp 3 carbons. Examples of such reactions are dehydrohalogenations with strong base, and acid-catalyzed dehydrations of alcohols. The opposite of an elimination is an addition reaction.
What are the products of an alkene reaction?
- The alkene attacks Hg (OAc)2, displacing acetate and forming a mercuronium ion (Step 1B). Next, the more substituted carbon is attacked by the solvent alcohol (Step 2). The resulting protonated ether is then deprotonated by acetate (Step 3F). Removal of mercury is done with NaBH4.
What is the difference between the haloform and Simmons-Smith reactions?
- This video covers the two common cyclopropanation reactions – the haloform and Simmons-Smith reactions. In both, an alkene reacts through a concerted reaction mechanism to form a cyclopropane in place of its pi bond. The first reaction proceeds through an unstable carbene intermediate, while the Simmons-Smith utilizes the more stable carbenoid.
What is the mechanism for the addition of water to an alkene?
- A hydration reaction is a reaction in which water is added to an alkene. Hydration reactions can take place when the alkene and water are heated to near 100 o C in the presence of a strong acid, which acts as a catalyst. Shown below is the hydration of ethene to produce ethanol.
