A new, simple method for the preparation of several 4-(aryloxy)phenols (2a-d) and alkyl 2-(4-hydroxyphenoxy)propionates (3a,b) is described.These compounds are key precursors for the synthesis of important aryloxyphenoxypropionate herbicides (1a-d).The method uses the Elbs persulfate oxidation to convert phenol into 4-hydroxyphenyl sulfate (5).The free hydroxy group is then reacted with various aryl halides and alkyl 2-halopropionates.Mild hydrolysis of the sulfate group with boiling acetic acid then gives the products (2a-d) and (3a,b), generally in modest to good yield.

Abstract: A series of chalcone derivatives containing quinoxaline moieties were synthesized, and their antibacterial activities were evaluated. Antibacterial bioassays indicated that some of the compounds exhibited significant antibacterial activity against Xanthomonas axonopodis pv. Citri (Xac), Xanthomonas oryzae pv. oryzae (Xoo), and Ralstonia solanacearum (Rs) at the concentrations of 50 or 100 mug/cm3. 50% effective concentration (EC50) values of (E)-3-(pyridin-2-yl)-1-[4-(quinoxalin-2-yloxy)phenyl]prop-2-en-1-one against Xac, Xoo, and Rs were 6.72, 15.17, and 9.29 mug/cm3, respectively, which were better than those of bismerthiazol (44.31, 42.46, and 62.36 mug/cm3, respectively). Scanning electron microscopy (SEM) was employed to analyze the mechanism of antibacterial action of that compound toward Xac. Graphical abstract: [Figure not available: see fulltext.].
