The transformation of the herbicide bromoxynil (3,5-dibromo-4-hydroxy-benzonitrile) was studied upon direct photolysis in water and in the presence of added nitrite. The addition of nitrite reduces the transformation rate of the substrate, most likely due to competition for absorption of radiation, but induces the formation of nitro derivatives (3-bromo-4-hydroxy-5-nitrobenzonitrile, 4-hydroxy-3-nitrobenzonitrile) [140]. 

Problem 24.2 In hich of the following compounds would you expect intramolecular hydrogen bonding to occur u-nitroaniline, o-cresol, o-hydroxybenzoic acid (salicylic acid), o-hydroxybenzaldchyde (salicylaldehyde), o-fluorophenol, o-hydroxy-benzonitrile. 

Hydroxy-benzonitrile konnen so in waBrig-alkalischer Losung mit guten Ausbeuten in Hydroxy-benzylamine iiberfiihrt werden3.
