trifluoride etherate and 90% hydrogen peroxide (2:1–4:1 complex) has been found to be a useful reagent for promoting the benzylichydroperoxiderearrangement of readily oxidizable substrates bearing a free, basic amine. The use of this procedure for introduction of the C-4 phenol of the C-4/C-5 selectively-protected -catechol unit found in PDE-I and PDE-II, naturally-occurring phosphodiesterase inhibitors
