Abstract
AbstractThe 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 SRN1 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‐N 4‐ethyl‐N 6‐isopropyl‐1,3,5‐triazin‐4,6‐diamine (Atrazine, 11) with −SnMe3 ions affords the reduced and substitution products in liquid ammonia‐DMSO as co‐solvent.
