Quinolines 3a–f, 5a–f, and dibenzo[b,f][1,5]diazocines 4, 6 were synthesized in the presence of 0.5 equiv. of diphenyl phosphate (DPP) under microwave irradiation. The obtained yield of 6,12-diphenyl-dibenzo[b,f][1,5]diazocine 4 was higher when using anhydrous DPP than when using HCl, H3PO4, and CH3COOH.
