Organic Synthesis: Toluene -> Benzoic Acid -> Propyl Benzoate -> 1-Propanol -> Propene -> 2-Propanol

To synthesize the organic compounds in the given chain, we will need to perform a series of chemical reactions. Let's go through each step in detail:

1. Toluene to Benzoic Acid: - The conversion of toluene to benzoic acid involves oxidation of the methyl group to a carboxylic acid group. - This can be achieved by using a strong oxidizing agent, such as potassium permanganate (KMnO4) or chromic acid (H2CrO4). - The reaction typically takes place under reflux conditions with the addition of an acid catalyst, such as sulfuric acid (H2SO4). - The product obtained is benzoic acid [[1]].

2. Benzoic Acid to Propyl Benzoate: - The esterification reaction is used to convert benzoic acid to propyl benzoate. - This reaction involves the reaction of benzoic acid with an alcohol, in this case, propanol, in the presence of an acid catalyst, such as sulfuric acid (H2SO4). - The reaction is typically carried out under reflux conditions. - The product obtained is propyl benzoate [[2]].

3. Propyl Benzoate to 1-Propanol: - The hydrolysis reaction is used to convert propyl benzoate to 1-propanol. - This reaction involves the reaction of propyl benzoate with water in the presence of an acid or base catalyst. - The reaction can be carried out under reflux conditions or at elevated temperatures. - The product obtained is 1-propanol [[3]].

4. 1-Propanol to Propene: - The dehydration reaction is used to convert 1-propanol to propene. - This reaction involves the removal of a water molecule from 1-propanol. - The reaction can be achieved by using a strong acid catalyst, such as sulfuric acid (H2SO4), or by heating 1-propanol at high temperatures. - The product obtained is propene [[4]].

5. Propene to 2-Propanol: - The addition of water to propene is used to convert it to 2-propanol. - This reaction involves the addition of water across the double bond of propene. - The reaction is typically carried out in the presence of an acid catalyst, such as sulfuric acid (H2SO4). - The product obtained is 2-propanol [[5]].

Please note that the specific reaction conditions, catalysts, and reagents may vary depending on the desired yield and reaction conditions. It is always important to consult reliable sources and perform the reactions under appropriate laboratory conditions.
