Abstract The syntheses of the first examples of 2-aryloxy-2,3-dihydro-3-(4′-bromophenyl)-1H-naphth [1,2-e][1,3,2]-oxazahosphorin 2-oxides (3a-g) have been achieved from the reaction of equimolar quantities of l-(4-bromoonilinomethyl)-2-naphthol (1) with various arylphosphomdichloridates in dry toluene in the presence of triethylamine at 50–55 °C. 2-Benzyloxyl/aryloxy/arylthio/bis(2-chloroethyl)amino-2
