Regioselective nitration of phenols using Sr(NO3)2 or benzyltriphenylphosphonium nitrate in the presence of H2SO4-silica under solvent free conditions
Regioselective nitration of phenols using Sr(NO3)2 or benzyltriphenylphosphonium nitrate in the presence of H2SO4-silica had been realized under solvent free conditions. The reaction proceeds through the formation of nitronium ion, which attack the phenol ring preferential at ortho position in prese...
