The carbonyl carbon is electrophilic and can undergo nucleophilic attack by carbon, oxygen, sulfur and nitrogen-containing nucleophiles. In this tutorial, we will focus on oxygen-containing nucleophiles, which form hydrates, hemiacetals and acetals. This tutorial will cover 1. formation of geminal diols or hydrates and when this reaction is favorable 2. formation of hemiacetals 3. formation of acetals 4. hydrolysis of hemiacetals and acetals 5. acetals as protecting groups Ⓒ Macmillan Learning Step 4: The acetal formation mechanism is also reversible. The reaction can be driven in the forward reaction by using an excess of alcohol and driven in the reverse direction by using an excess of water. Analyze the reaction shown: excess H₂O* ? Select the product(s) of the reaction. OH HOCH₂CH₂OH Å -OH

we know that ethers, such as diethyl ether and tetrahydrofuran, are quite resistant to the action of dilute acids and require hot concentrated HI or HBr for cleavage. However, acetals in which two ether groups are linked to the same carbon undergo hydrolysis readily, even in dilute aqueous acid. How do you account for this marked difference in chemical reactivity toward dilute aqueous acid between ethers and acetals?
For butenafine, develop a synthesis that starts with napthalene and benzene. (aromatic methyl groups can be converted to alkyl bromides using Br2/light, and aldehydes by heating the alkyl bromide in DMSO, eg. ArCH3 to ArCH2Br then to ArCHO).
The following are intermediate products in the stepwise synthesis of compound 1 from benzene. Give the correct sequence of reactions with the appropriate reagents that will lead to the correct intermediate products and final product.
Butanone undergoes a nucleophilic addition with a Grignard reagent made from 1-bromopropane and magnesium metal in THF solution. The alkoxide formed from the nucleophilic addition is then conveted into the final product by the careful addition of dilute acid. Complete the mechanism by following the instructions provided for each step. Step 1. Nucleophilic Addition in THF
Please give the appropriate reagents FOR 3 and 4 to complete the following synthesis. ******** Keep mind, H2/PD does NOT go into 3 and KMNO4 does NOT
Propose multistep syntheses usingketones and aldehydes as startingmaterials and intermediates. Protectthe carbonyl group if necessary
Like other strong nucleophiles, triphenylphosphine attacks and opens epoxides. The initial product (a betaine) quickly cyclizes to an oxaphosphetane that collapses to an alkene and triphenylphosphine oxide. Show how this sequence might be used to convert cis-cyclooctene to trans-cyclooctene.
The following bicyclic ketone has two -carbons and three -hydrogens. When this molecule is treated with D2O in the presence of an acid catalyst, only two of the three -hydrogens exchange with deuterium. The -hydrogen at the bridgehead does not exchange. How do you account for the fact that two -hydrogens do exchange but the third does not? You will find it helpful to build models of the enols by which exchange of -hydrogens occurs.
