  1. In the reduction to benzene, should the reactant be H3PO2 instead of H2PO3? That is how I have seen it elsewhere.

  2. Hi, in the Examples the example 4: Ph-N+N + H3PO2 —> “benzene”. Why in the reaction Ph-N+N + HPO —> is produced “phenol”? Its is ok the other reaction? Thx, P.

  3. Hi, is the carbon C, where is bonded -N+N, the same carbon where is bonded the X from the Description? Thx, P.
