The dehydration of alcohols Under acidic conditions, alcohols will undergo a dehydration reaction, producing an alkene and water. During the reaction, the hydroxyl group of the alcohol and a hydrogen atom from an adjacent carbon atom are lost. The reaction takes place in three steps, as shown in the diagram. (Figure 1) In the first step, a hydrogen lon bonds to the hydroxyl group of the alcohol. In the second step, the protonated hydroxl group leaves the compound,...

13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as Syl (substitution, nucleophilic, unimolecular) and S2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Snl route, primary alcohols follow the S2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Sul reaction involves rapid protonation of the alcohol, followed by the...

1) Choose one molecule from the set and create an 8-step synthesis scheme using the chosen molecule as your starting material. You need to write the complete set of reagents and draw the product expected from each step. Reagents typically used together are considered one step, eg. 1) LAH 2) H.O should be considered as one step Your 8 steps must include at least one reaction from each of the chapters, aldehydes and ketones, carboxylic acid derivatives, alcohols. You can...

1151 VCL 11-8: Claisen Condensation -1 For this assignment, the target compound that you should synthesize is methyl acetoacetate. This is another carbonyl addition variation. Examine the product and determine which ester is the nucleophile and which is the electrophile. Keep in mind the mechanism and that you need to acidify the intermediate in order to isolate a neutral product. Synthesis Procedures 1. Start Virtual ChemLab and select Claisen Condensation-I from the list of assignments in the electronic workbook. After...
