The effect of addition of Lewis acid B F 3 before the reduction of S-ethyl thiobenzoate (A) is to be explained. Concept introduction: The lithium aluminum hydride reduces the thioacetate to thiol similar to ester reduction. If the reduction of thioacetate carried out by addition of Lewis acid B F 3 it gives cyclohexyl ethyl sulfide due to formation of tetrahedral intermediate having oxygen-boron bond.
