In our studies on the development of new promoters for the root formation of tree cuttings, 4- trifluoromethylindole-3-acetic acid (4-CF3-IAA), a new fluorinated auxin, was synthesized via 4-trifluoromethylindole and 4-trifluoromethylindole-3-acetonitrile by using 2-methyl-3- nitrobenzotrifluoride as the starting material. As a control compound for comparing biological activities, 4-methylindole-3-acetic acid (4-CH3-IAA) was also synthesized by using 2, 3- ...
