The following question was on one of the tests we had recently
Now i worked out the intermediates and the product as follows:
The first step is an intramolecular Cannizzaro reaction in which the aldehyde is oxidised to acid and the ketone reduced to base
In the next step decarboxylation takes place and we are left with benzyl alcohol (B)
Oxidation of (B) using Pot. Permanganate gives benzoic acid and decarboxylation of benzoic acid using soda lime gives us benzene as the final product which is the correct answer to the question.
Now i am quite satisfied with the validity of all the other steps excluding the acidic decarboxylation of the alpha-hydroxy acid
Can someone explain to me the probable mechanism for that reaction?
Or correct any other mistake i may have made in any of the other steps/conversions
