Question

Using cyclohexane as your starting material, show how you would synthesize each of the following compounds. (Once you have shown how to synthesize a compound, you may use it as the starting material in any later parts of this problem.)
a. bromocyclohexane
b. cyclohexene
c. ethoxycyclohexane

Accepted Answer

Step 1: To synthesize bromocyclohexane (compound a) from cyclohexane, perform a free radical halogenation reaction. Use bromine (Br₂) in the presence of ultraviolet (UV) light or heat to initiate the reaction. This will result in the substitution of one hydrogen atom on cyclohexane with a bromine atom, forming bromocyclohexane. Step 2: To synthesize cyclohexene (compound b) from bromocyclohexane, perform an elimination reaction. Use a strong base, such as potassium tert-butoxide (KOtBu) or sodium ethoxide (NaOEt), in an alcohol solvent. The base will abstract a β-hydrogen, leading to the formation of a double bond and producing cyclohexene. Step 3: To synthesize ethoxycyclohexane (compound c) from cyclohexene, perform an electrophilic addition reaction. First, react cyclohexene with ethanol (C₂H₅OH) in the presence of an acid catalyst, such as sulfuric acid (H₂SO₄). This will result in the addition of an ethoxy group (-OCH₂CH₃) to the cyclohexane ring, forming ethoxycyclohexane. Step 4: Ensure that each reaction is carried out under the appropriate conditions (e.g., temperature, solvent, and catalyst) to maximize yield and minimize side reactions. For example, control the amount of bromine in Step 1 to avoid over-halogenation. Step 5: Verify the structures of the synthesized compounds using spectroscopic techniques such as NMR or IR spectroscopy to confirm the success of each reaction.
