- The Dess–Martin reaction reacts an alcohol with the Dess–Martin periodinane. The first step displaces one of the acetate groups on the periodinane with the alcohol. A base then deprotonates one of the alpha protons, forming a new carbonyl bond, iodinane and acetic acid. The oxidation stops at this stage to give the aldehyde. Both Swern and Dess–Martin conditions will also convert a secondary alcohol to a ketone. Now apply what has just been discussed. Draw the major organic product.Thiols or thiol (-SH) group is a better base than hydroxide (-OH) group in elimination reactions.What happens when water, alcohols or other protic solvents are used in Grignard reactions?
- Label sets of equivalent hydrogen atoms on the alcohol product using alphabetical notation a, b, c etc.As we have seen in this chapter, carbon-carbon double bonds are electron-rich regions that are attacked by electrophiles (e.g., HBr); they are not attacked by nucleophiles (e.g., diethylamine). However, when the carbon-carbon double bond has a carbonyl group adjacent to it, the double bond reacts readily with nucleophiles by nucleophilic addition (Section 19.8). Account for the fact that nucleophiles add to a carbon-carbon double bond adjacent to a carbonyl group and account for the regiochemistry of the reaction.In Chapter 18, we will learn about the hydrolysis of acetals to aldehydes and ketones. Four of the seven steps in the mechanism for this process are shown in the conversion of acetal A to hemiacetal E. a.Add curved arrows for each step. b.Draw another resonance structure for C. c.Identify the nucleophile and electrophile in Step [3]. d.Which steps are Brønsted–Lowry acid–base reactions?
