A series of functional metallophthalocyanines have been synthesized to study their role as a catalyst towards the reductive dechlorination of atrazine using sodium borohydride as a mild reducing agent. The cobalt(II) phthalocyanine bearing nitro groups at the peripheral position is the most efficient catalyst with exceptionally high catalytic activity in comparison to other functional cobalt(II) phthalocyanines.
Trimethylstannylation of mono- and dichloroarenes by the SRN1 mechanism in liquid ammonia

The photostimulated reaction of methyl 2,5-dichloro benzoate (1) or methyl 3,6-dichloro-2-methoxy benzoate (7) with -SnMe3 ions give good yields of the disubstitution products by the SRN1 mechanism in liquid ammonia. Conversely, in dark conditions, substrate 1 reacts with -SnMe3 ions to afford the mono-substitution products by the S RN1 mechanism. On the other hand, substrate 7 reacts with -SnMe3 ions in dark conditions to give mono-reduced product probably by a halogen metal exchange reaction. In addition, the photostimulated reaction of 2-chloro-N4-ethyl-N6- isopropyl-1,3,5-triazin-4,6-diamine (Atrazine, 11) with -SnMe 3 ions affords the reduced and substitution products in liquid ammonia-DMSO as co-solvent.

Electrocatalytic dechlorination of atrazine
Stock, Naomi L.,Bunce, Nigel J.
, p. 200 - 206 (2002)
Atrazine (2-chloro-4-ethylamino-6-isopropylamino-s-triazine), a photosynthetic inhibitor that is used in large quantities for weed control in corn and sorghum, is dechlorinated in aqueous solution upon electrolysis at a reticulated vitreous carbon cathode
Rapid reductive dechlorination of atrazine by zero-valent iron under acidic conditions
Dombek, T.,Dolan, E.,Schultz, J.,Klarup, D.
, p. 21 - 28 (2000)
The dechlorination of atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) via reaction with metallic iron under low-oxygen conditions was studied using reaction mixture pH values of 2.0, 3.0, and 3.8. The pH control was achieved through addit
Kinetic and mechanistic aspects of the direct photodegradation of atrazine, atraton, ametryn and 2-hydroxyatrazine by 254 nm light in aqueous solution

, p. 498 - 503 (2007/10/03)
Atrazine (1), Atraton (2) and Ametryn (3) are photodegraded upon 254 nm irradiation, yielding 2-OH-atrazine (4) as a photoproduct. Dealkylation products are also generated, and 4-ethylamino-6-isopropylamino-(1,3,5)-triazine was also found as a photoproduct of 3. The main photoreaction is proposed to be an addition-elimination, yielding 4, which subsequently photodegrades. The ease of photodegradation depends on the electron availability at position C-2, the observed order of photoreactivity being 1 > 3 > 4 > 2. Copyright
