- Isoprene has sometimes been used as a starting material in the laboratory synthesis of terpenes. In one such synthesis, the first step is the electrophilic addition of 2 mol of hydrogen bromide to isoprene to give 1,3-dibromo-3-methylbutane.Write a series of equations describing the mechanism of this reaction.arrow_forwardCompounds with more than one hydroxyl group can react with thionyl chloride differently from simple alcohols.

- Enamines normally react with methyl iodide to give two products: one arising from alkylation at nitrogen and the second arising from alkylation at carbon. For example, Heating the mixture of C-alkylation and N-alkylation products gives only the product from C-alkylation. Propose a mechanism for this isomerization.arrow_forwardReaction of -pinene with borane followed by treatment of the resulting trialkylborane with alkaline hydrogen peroxide gives the following alcohol.

- Both cis- and trans-2-methylcyclohexanol undergo dehydration in warm sulfuric acid to give 1-methylcyclohexene as the major alkene product. These alcohols can also be converted to alkenes by tosylation using TsCl and pyridine, followed by elimination using KOC(CH3)3 as a strong base. Under these basic conditions, the tosylate of cis-2-methylcyclohexanoleliminates to give mostly 1-methylcyclohexene, but the tosylate of trans-2-methylcyclohexanol eliminates to give only 3-methylcyclohexene. Explain how this stereochemical difference in reactants controls a regiochemical difference in the products of the basic elimination, but not in the acid-catalyzed elimination.arrow_forwardYou are given a mixture of benzoic acid, 2-naphthol and 1,4-dimethoxybenzene and you are asked to separate the mixture into its following compounds. You are limited to using dichloromethane, pentane, cyclohexane and ethyl acetate as organic solvents. This doesn't involve solvents used to convert the 3 compounds to ionic salts. Suggest possible organic solvents and explain a procedure you would carry out to separate the 3 mixtures briefly.arrow_forwardThe following reaction has been reported in the chemical literature and gives a single organic product in high yield.
