why are we using H3O+ in the case of preparation of aldehydes in Stephen reaction while in case of hydrolysis of imine using diisobutylaluminium hydride we are using H2O.What is the reason behind this?

Expert Answer:

We are using H3O+ in the case of preparation of aldehydes in Stephen reaction because the hydrolysis reaction is slow.so this reaction is catalysed by acid(H+).
 
while in case of hydrolysis of imine using diisobutylaluminium hydride we are using H2O for the hydrolysis of the product formed by the reaction of nitriles with diisobutylaluminium hydride,
