Benzene diazomium salt + h3poc acid?

Question

benzene diazomium salt + h3po4 acid what is the end product?

Answer 1

  Are you sure it is H3PO4  and not H3PO2 ?The reaction of a diazonium salt with hypophosphorous acid, H3PO2, results in replacement of the N2 group by an H. This is an efficient way to remove an aromatic amino group.

Answer 2

you get benzene back, if phosphoric acid is what you meant to say because i dont know what H3POC is.
