At first, glucose reacts with phenylhydrazine giving glucosephenylhydrazone by elimination of water molecule from the functional group. Then one mole of glucosephenylhydrazone reacts with two molecules of phenylhydrazine.

The mechanism includes first the oxidizing of the alpha carbon to a carbonyl group followed by the removal of one water molecule.
