ether-phosphate structural motif. The synthetic route to bis-aryl phosphates 2 and 3 consisted in two nucleophilic substitution reactions with amines from cyanuricchloride, followed by a Suzuki coupling with the resulting 2,4-diamino-6-chloro-1,3,5-triazine derivative 12 to introduce the diaryl ether functionality. Aryl phosphate 4 was obtained via condensation of aryl guanidine 34 with aryloxyphenyl butenone 31
