An improved general synthesis of substituted dibenzo[1,4]dioxines I (R = H, 1-Cl, 2-Cl, 1-NO2, 2-NO2, 1-CO2R1, 2-CO2CHMe2; R1 = H, Me, CHMe2) by reaction of 2-HOC6H4OH and R2C6H3R3R4-1,2 (R2 = H, 3-Cl, 3-NO2, 3-CO2R1, 4-Cl, 4-NO2; R3 = R4 = Cl, F, NO2; R3, R4 = Cl, NO2) with K in HMPA is reported. The yields are generally superior to those in published methods.
